This is Tekan plug in by Riz- Tekan — Kanban that stays with you which is basic version and hasn’t been updated since long time.
There is another advanced version of Tekkan which is not available as a TW plug in - My Tekan — A kanban that stays with you Source code- GitHub - ibnishak/Tekkan: A Node based offline Trello Clone mainly for debian systems
Also there is a basic version of Tekan in Tiddlywiki XP - TiddlyWiki xp — A chance to experience TiddlyWiki very quickly
Can someone make the advanced version of Tekkan into a TW plug in. I tried many times, but I couldn’t get everything working properly.
