I find myself repeatedly having to either add or remove fields from the main panel. I want a different mix, depending on the view and what I'm doing, likewise column widths. Changes to fields and widths made in one view seem to get propagated to other views, but it's not clear when and how. It feels like I'm doing a lot more messing with this than should be necessary.
Probably related, how independent are the different tabs? Like, which changes in one are also made in others? What determines that?
Also, does the backward/forward navigation in the tab apply only within that tab. It seems like each tab has its own history. But it's hard to be sure.
Also, I find that the horizontal scroll bar sometimes disappears, or is it that it only appears in some views, under some circumstances?
The common thread here is the difference between local and global effects. Whether or not a panel's open/close status carries over from one node to another is another source of some confusion.
