 - I guess it's pretty dangerous passing pointers everywhere?
-- kill process using command in window
+- text in events aren't we using invalid memory for text? We need an intern table?
 - kill all processes on exit https://devblogs.microsoft.com/oldnewthing/20131209-00/?p=2433
 - if exec is prepended with '!' symbol then run a shell command
 - try using git grep for search for now, combine with fuzzy search buffer
 - Test stdin writing code
 - Implement shell interaction (last line should have a '$'' symbols, if you press enter it should send that line to stdin of a running shell)
 
-- open file from cmd
-- detach from console when executing the program from the console to make sure that the user won't have to keep the cmd alive
-- win32 open file with text editor from desktop
-- drag and drop file into the window
 - exe icon
 
 - search as a command to execute which is going to be in the title bar
