Dear Chris, Reinhard, X-Air, and WeatherCat welcome wagon, . . . .
Welcome back Chris to the WeatherCat forum! . . .
. . . .
I?m not sure whether to be pleased or a little disappointed that weathercat is so similar to what I remembered.
. . . .
I'm not sure exactly what you were looking for in terms of changes to WeatherCat, there are some important updates that are very useful once you get used to them. Custom Text Windows are extremely handy. Synthetic channels are also very useful if you have to be willing to get your hands dirty with AppleScript.
WeatherCat has also been forced to "adjust" to the changing environment. It has had the ability to upload to Twitter for some time, but Stu had to completely rewrite that functionality when Apple removed the APIs from macOS. So simply keeping WeatherCat the same has been harder than it should have been.
Once more - welcome back!
Cheers, Edouard
