Reverse list of commands in command history tool
Assign unique integer IDs to each session. Use them to tell if a mark belongs to a particular session and bold it in the command history tool.
Make CommandUse track directory each command was run in. Alt-doubleclick in the command history tool outputs a cd command to that directory if available. Also fix a bug where the command history popup didn't scroll to the top/bottom of the table when opened.
refactor command history stuff into one file per class
Refactor expose in to separate files
