So, I finally mashed together a working .desktop for Anaconda. Looks like this in essence (this is the generalisation except for Category, and AppsData is just a place I put everything that's not via the Software "store"):
Comment=This app does something
This works fine. After trying to copy paste from others, trying out Arronax and then mashing it all together. Great learning experience
But.... the categories and how they work is totally bonkers. It seems every application have different ways of writing them. For instance, "Utility" is marked red but plain words seem to be used in many .desktop files. The app Barrier for instance have only "Utility" and ends up in "Accessories". Complete chaos
Can someone point me in the right direction on what the categories are in Zorin (if they are specific)?
Also, when I try to make one for Blender it looks like this (apart from that the svg doesn't work as an icon):
Comment=3D modeling and animation studio
But I get all kinds of errors.
Why is this process not automated? Installing the LATEST software and have it show up in a category etc (i.e. properly "installed") can't be rocket science.
Forgot to mention: I'm aware I can get the latest Blender in the software store, but I really want to understand how .desktop works.
