Offline Kanban (Beta)
Offline Kanban solves the problem of the modern hobbyist, DIYer and even small business providing an affordable, almost completely offline one time purchase product to use a digital Kanban board with little set-up. Better than sticky notes but still belongs to you, data and all.
Linux: The most tested platform, tested with Linux Mint, Kubuntu and Fedora(KDE).
Mac: I don't own the hardware, so it is extremely lightly tested. It also involves enabling 3rd party apps on the OS.
Windows: Cards move on right click when they shouldn't, otherwise now working!
Note: By beta we mean this product is ready to use but missing some quality of life features (like multi-language settings) and may have some bugs. This app is provided free of charge but any money is appreciated! The code is also open source (GPLv2) and is provided through Github.
