 - Make a fuzzy command !> grep and fuzzy over it??? (doesn't seem very useful for grep)
 - Add Bool variable
-- Not rendering U+0009 TAB properly 
+- SetWorkDir should rewrite the buffer name paths for special buffers
 
 - Initialize all keybindings at the start and refer using global variables?
 - RegisterCommand should_appear_in_listing variable
 - Maybe one list for all variables including the commands etc?
-- Problem generating configs don't know which quotation marks would be good ....
 
 Use session 3:
 - Maybe status view, commit changes (like to buffer name or line) on enter?
 
 How to go about search/replace, opening code and other considerations
+- Search and replace sign Find@>ReplaceWith
 - We can use sed + find to search and replace, the automatic reopen should do the job
 - Maybe also we can List all files recursively instead of opening them, how fast is that???
 - For fuzzy find number of files is the problem - most likely just getting them in one place is the biggest problem that can be optimized
