This ain't a small project so I need some scratchers to contribute, review and suggest. Here is a glimpse…
Willing to contribute for: (Short time, long time)
Working on: (App, Animation, Art/Icons, Design, Specific feature like paint/notepad, etc.)
I will add your work to the project if it is feasible and good enough, with proper credit and some modifications.
To submit your work, (like a notepad) you can simply make a new project and try to refrain your work in a single sprite. (You can also remix my project if you like)
You can comment on the project or the forum to suggest or request a feature. Just put “Suggestion” on the top.
