I like the option to save as desktop item with all my preferences, When I copy or move large files from a directory in one window to a directory in an other window, at least the "source" window is "locked" and can not be used as long as the copy/move is running. Can't you start that copy/move process in the backgroud so that the window is free again?
The directory size How do I enable the "Optional display of the directory size and directory content in the status bar"?
Can we have support for 7zip files. I cannot use it as a default file explorer as i cannot make it default. I also find it a little slow because of i think 4 windows opened at a time, it takes time to open the tree so there is a need to may be do something to improve speed. Its color can also be toned down to match windows colors (or may be option to change colors).
