I haven't touched SkywarnPlus in a long time - since before my daughter was born. I just don't have the time. I had a lot of ideas and had planned on starting work on a much improved release of SWP at some point... but after sharing those thoughts with the wrong person, they decided to rip off my ideas and even the name of my project for their own personal gain, with absolutely zero attribution given to the original project. This was quite discouraging, and caused me to completely lose all interest in putting forth any additional time or effort into SkywarnPlus.
Maybe one day I'll upgrade to Deb13 myself and have to get around to fixing some things so I can run SWP on my own machine(s). Maybe I'll share those fixes.
Anyways, I wouldn't hold my breath waiting on any updates to SWP. Sorry. I would say that my project is open to contributions and pull requests if anyone else wants to help, but it seems that's just wasted breath as folks nowadays would rather just copy/paste (not even fork) someone elses project into an AI for a few "upgrades" and then pass it off as their own "original" project.
