Panes are pain

1. When I click something, I expect it to open in the current Pane I’m on. Not every link opens in the left one. Even if it’s from the page on the right Pane.

2. Seems like navigation on internal Feedback page doesn’t work right. From time to time I can’t go back to previous page. CMD+Z doesn’t work, back arrow stays dimm.

3. I think it would be better to have 4 Panes max. Dividing the space not only vertically, but horizontally also.
User should have ability to open from 1 to 4 Panes in every position and drag content from one to another. And with right click on every link could be a choice “Open in Pane upright, upleft, downright, downleft“.
