the title says it all. i like having the tree visible, but i don't like the fact that it follows my activity in the active pane. i want it to stay as i left it. is this possible?
also, i have noticed that some portions of the screen have outlines, and i remember seeing settings to turn these outlines on/off. is it possible to draw borders around the source/destination pane headers? i like my destination pane header to be coloured the same as the surrounding area, but it would be nice to have some visual marker between them. (my folder tabs are on top, so that's where the lack of delineation is visible)
Click the lock icon next to the tree's close button and it will stop following the file display. Click it again to return to normal.
If you don't have Opus set to update the Default Lister automatically then you should use Settings -> Set as Default Lister to make the tree-lock setting stick.
About the other question (BTW, please ask unrelated questions in separate threads), there are no options to draw additional borders but you could get the same result by creating a suitable background image and tiling it across the Folder Tabs area. (Preferences - Display - Images)
