Drag-n-Drop to rearrange Window order would be very useful.
Additionally, it would be quite useful (IMHO), if the Window order was saved in the desktop based on order-of-appearance in the Window List.
Right now the desktop file (on application startup) seems to order the Window List based on reverse active order. If you click on each Window in the list (in your desired order), starting with the Window you want at the top of the list, close PLSQLDev, and re-open PLSQLDev; the windows seem to be arranged in the order they were accessed.
A collapseable outline Window list, with defineable (level 0) outline groups, with drag-n-drop, saved with each project would probably be on my unatainable dream list, wouldn't it?
...just thought I would ask...
