1. When drive combos enabled for explorer panel and MC window size is quite small, buttons (tree, root etc) are not visible.
I see 3 ways to resolve this.
a) Additional button (like arrow button in old MS Office toolbars) may appear which shows something like popup menu with inaccessible buttons
b) Bar wrap, i.e. buttons which don't fit bar width should be shown at next line
c) Additional toolbar (like drive bar)
Yes, That is something would like to fix. But there is no easy way to fix so that it will auto correct it self if the window is resized.
All good solution would require a lot of work. And I would categorize it is a minor issue and it would cost to much develop time to fix it.
But I put it on the list. So maybe I get a good idea someday and can fix it in a easy way.
2. Current file info. This was already suggested but it is especially actual now because of list mode.
In list view mode you can't see current file info (size, date, attr ...), so maybe a section in status bar can be used for that?
Yes, Something like that is planned. I will push it higher up on the todo list.
