This video will help you to arrange Snow Owl’s user interface to accommodate your needs. It demonstrates how to create a customized perspective by changing the size and layout of the visual components.

This is the second part of the introduction to Snow Owl. You can find the first video at:

In this video I will show you how to set up your workspace according individual preferences. I’ll demonstrate how to change the size and the layout of the visual elements and how to create a customized perspective.

We already talked about the preset perspectives so the preset layouts of the user interface that come with Snow Owl. What you see here is the authoring perspective that gives you access to most of the functions of the software.

If you do a mapping, you might want to use the mapping perspective by just clicking this icon in the toolbar where you see the SNOMED CT concept views on the left side and the refset view and on the right side the ICD-10 view and the editor in the middle so you can map from one terminology to the other.

If you’re working with refsets, the refset perspective might be handy because it has only the refsets view and the editor. So if you’re opening a refset for instance this one, then the editor will be displayed and the whole screen can be used just for the refset view and for the editor.

Let’s go back to the authoring perspective. You see now our reference set editor is already here in the middle.

Let’s start with opening and closing views and editors. It’s quite simple. You just press, click this close icon you can also right-click a tab and then close it here. So if I would like to have more space, for my SNOMED CT concepts I can simply close all the tabs in the section below and then this window will be expanded. You can of course also expand the size of a window just by simply dragging the border. But if you don’t need a view, it makes sense to close it then the whole section disappears. I’m going to close this one as well. And now you open a concept and you’ll have a lot more space for the editor or for several editors.

If you want to close an editor, you can right-click it and there is the option of closing all editors at the same time or closing the others, so not the active one but all the other ones. Let’s do this. You see now the other one disappeared. If you have a lot of editors open, what is going to happen is that a small symbol will appear that shows you that some editors are hidden and you can click it and then the one that is in bold is actually the hidden one and if you click it, then this one will be open. You can either close all, just this one, or close all the others. Let’s close them all.

So if you’re happy with this view, with this perspective, you can save it by clicking Window > Save Perspective and then you can type in a name for your perspective. I already created one, that’s called “browsing” that I’ll overwrite now, and then I click OK. It warns me that I’m overwriting the perspective. There is no function to delete a perspective so you might want to overwrite one that you don’t need anymore. Now actually, on the Owl icon, this is my customized perspective. If I go to reference set for instance and then I go back I have my “browsing” perspective.

If I’d like to have the authoring perspective again, I need to go to Window > Open Perspective and there’s authoring. If you go to other, you have access to all of the perspectives that are out there so you see there’s some authoring default perspective. If I click it, I get my authoring perspective back and there’s actually two owls now one is for the browsing perspective and one is for the authoring so I can switch perspectives.

A few things I haven’t talked about is you can move a view by grabbing a tab and moving it to the side and you see when I grab it and I keep the button pressed then the mouse pointer changes in a stack and then I can just drop it in this stack or I can drop it as part of another stack or down here.

However, there’s another possibility. I’ll show this to you with editors. Let’s open two editors I grab this and it turns into an arrow then it will be docked on the side of this section. So I have two editors side by side. Now if I double-click this and then I use the entire screen, this is quite useful when you’re editing, and when you want to have two editors side by side. I’ll make it smaller again.

Another function is minimizing and maximizing. You can maximize a window simply by double-clicking the tab. When you double-click it again it restores it or you can maximize it with this icon and then there’s this little restore icon on the side. This works as well with some editors. Double-clicking for instance the reference set editor double-click it again, restores it, maximize and restore so you can either use this or you can double-click and you can use that it doesn’t matter what you do, either double-clicking or using the icons.

Whenever you maximize a view or an editor all the other components will still be represented by icons here in a trim stack. Trim stacks will appear and with these you can restore the section like here, so now we’ve restored it. Let’s do it again. So you’ve restored it but if you just want to look at one of the views you just click the icon and you can see, the tool tip shows you which icon it is for instance ICD-10 terminology you just click this and then it kind of opens up like a drawer that is above on top of the reference set editor. If you click it again, or if you click somewhere else, it disappears. So it doesn’t really open it up but puts it on top of it. You can do this with all the other things if you need bookmarks for instance or if you want to have the task list just like this. So you’ll still have access to all of the other elements by clicking these icons or if you want to restore it just click this or double-click.

That was basically all I wanted to say about changing your layout and that’s it for now. Thank you!
