I couldn't find any posts about this issue sorry in advance if its been dealt with already. I think if the file browser was changed to not resize the design workspace it would make the software much more seamless. The issue is if you like to hide the browser to focus on the model, then the workspace resizes and you go through the same thing when you want to open another model. The resizing practically stops the software for a few seconds, depending on your model's complexity it can take 5-6 seconds for the resizing which becomes bothersome if you need to open and close files multiple times. My solution is to let the browser hover over the workspace, without resizing and hide back after clicking on the workspace.
