FEATURE SaveAll dirty files which are saved on disk already but dirty
DESIGN try to make console less special, make stuff reusable etc.
DESIGN Config file versions, when loading should be checked, at the top of the file, what to do when old version?
ISSUE Ctrl+Alt+Down (DuplicateLine) doesn't work on ubuntu
@@ -9,32 +8,21 @@ FEATURE KillConsole, or maybe some window targetting but how??
ISSUE I hit a case where GC tried deleting a buffer which was not attached to the buffer list, it had zeroed next, prev. It happened after iterating through directories using the ctrl + period
FEATURE Search whole words, case sensitive etc.
FEATURE Select all searched occurences
DESIGN Indicate maybe on the console border that a process is running in the console! also maybe exit code when exits
PLATFORM Fix windows build
ISSUE What to do / how should Reopen work after we delete the file on disk in some other program?
- Changing window properties by changing the window name?
- commands for scrolling: center, cursor_at_bottom_of_screen, cursor_at_top
- Add metadata to Lua bindings so that we would get a better listing (function args?, what else?)
- Kill buffer command (it should be marked for deletion and deleted at the end of frame!)
- Delete directory/file on disk command
- Check. Convert more commands to taking buffer instead of view
- Check. Rewrite more commands to use already implemented commands?
- Lua namespaces for different kinds of commands (by ids, using main_set, using active_set)?
- Some decl/function indexing in fuzzy format
- Fix jump scroll, the query ends up the last line on screen, kind of wacky
- LoadWord, EncloseWord configurable?
- dump text editor state to file, restore state
- proper lister
- ask user if he really wants to quit even though he has an unsaved buffer - popup window | we could just show ForceClose() in the titlebar
- Find matches using grep, change things in that buffer then apply those changes to all items
- group history entries so the you can rollback through multiple ones at once and not waste time on skipping whitespace trimming or deleting every character

- Search and replace
- A lister which is going to show project without the full path and sorted by recency
- word complete
- Search all buffers in 10X style, incrementally searched results popping up on every key press (maybe we need coroutine library in C so this is easier?)
- escapeing multiple cursor after ctrl + d should put the cursor where it was (probably will need to swap secondary and primary cursor for new cursor
