New UI buffer thing

 Use session 1:
 - OpenCommand in command window freezes the app
-- Shift + backspace should delete normally
 - SDL popups are not working on linux ...
+    - CloseAll idea: should create a buffer interface with list of buffers, user would be able to select which buffers to save and which not, then button UICloseAll
 - Creating files more efficiently
     - Dialog popup on save? Or ctrl-shift-s?
     - Maybe rename in bar and do :Rename
 
+New UI Session
+- Cleanup String16/String with Open and EvalCommands after lua refactor
+- Rename GotoBackward and others to Jump
+
 - Open with seek string (open at pattern) filename:32 filename:/^Window$/
 - build console window
 - Show what process/coroutines are running and allow to kill (active process buffer?)
