Trying out XYPlorer again. 6 general questions

[vrtarifaachen]

1) How do I have alt+F4 minimize (not close) XYplorer? I never want to close XYplorer unless I right click tray and click "exit".

2) This follows up on question #1. How to program a user-button to bring both panes to "default folders"?

3) I want to change the focus color of inactive pane (to a darker color). Possible?

4) This is a major one. As of right now, CTRL-Z tries to UNDO a closed tab. I love this functionality, but it really sucks if you delete a file, only to find out you cannot undo the file delete. Is there a way to Undo file delete instead of undo last tab, and assign undo last tab to CTRL+SHIFT+Z?

5) Any way to put NAME of Portable-file-associated program in a special column? (For example, .txt would have "Notepad++ in this field)

I will probably come up with more questions as I use it more.
