Eldit (still being made)

wget https://raw.githubusercontent.com/LDDestroier/CC/master/eldit.lua
|

|
||||
TO DO:
|
||||
- MAJOR: Merge selections that intersect
|
||||
- MAJOR: Allow selecting with Shift + ArrowKeys
|
||||
- MAJOR: Fix deleting multiple selections (MUST delete selections from bottom to top)
|
||||
- MAJOR: Add syntax highlighting
|
||||
- Add more keyboard shortcuts
|
||||
- Add help menu
|
||||
- Eventually add simultaneous peer editing
