I always wondered what could be done with some additional video editing time to my hands, not sure if you feel the same? So many clips we take and we could make so many awesome montages, but in the past its only ever been @Greboth and @tronic44 having the capability and time to do them based on their knowledge.
I also think there could be some time invested in some graphic apps too. Especially the ones that make Vectors and other ones that make svgs. Inkscape is the one I'd want to get more of an understanding on as its 1, free, but 2, you can create some great things within it for lots of things out there.
Last thought would be is there anything that your hobbies connect to at all that you can see something you want to creatively do in it? Might help narrow down some other apps perhaps.
