## Todo
- git integration to `git clone` the [ircart](https://github.com/ircart/ircart) repository & `git pull` on `.ascii sync` *(Load art files into RAM for faster pumping)*
- `.ascii scroll` command to loop playing random art files *(Stopped with `.ascii stop`)*
-- Add arguments to `.ascii img` for contrast, brightness, * effects *(Take them out of self.settings)*
+- Add arguments to `.ascii img` for palette, width, & other options
- Setting to auto convert any image link to IRC art *(Emulate link previews like on Discord LOL)*
- `.ascii record` to record lines from the senders nick for uploads *(Stopped with `.ascii stop`)*
- Improve randomness with `.ascii random`
