 - Window position: vscode opens in fullscreen and then remembers what position it was close in (could be a config option)
 - On Linux: Try to implement is_debugger_present()
 - Maybe IPC for te.exe when it's already open and file arguments are passed it should perhaps open a buffer in current window??
-- Add <<File>> <<ProjectDirectory>> template strings to Open (Then remove SEtWorkdirhere)
+- Add <<File>> <<ProjectFolder>> template strings to Open (Then remove SEtWorkdirhere)
 - :Set Filename to name current buffer ??? :O and others like that!!
 - Make a fuzzy command !> grep and fuzzy over it??? (doesn't seem very useful for grep)
 - Make the equivalent of SearchOpenBuffers but for cmds like !@git grep -n "@>"
