I am not related to the GIMP project. To me, it seems that your story caused much anger in you. Perhaps I can take some anger out of this discussion and push things to a constructive solution.
- “Icon table” - you mean the toolbox, right?
@jakedane already pointed out how to solve this. You might also find the information in GIMP’s help useful.
Some background information: Based on a pretty structured feature request in 2015 this design was introduced in 2020 with GIMP version 2.10.18. The goal was to support users with small laptop screens to handle the many features in the toolbox. As I can see, there was a short discussion among developers in the bug tracker. I neither see nor know whether they based this design decision upon user research or discussing alternatives, such as fewer features, hiding rarely used features from the toolbox, verifying the proposed grouping or finding a good default set of shown tools. I doubt this took place, but somebody with a deeper knowledge about the development process at this time can correct me.
Currently, their bug tracker holds some open bugs about toolbox grouping. Perhaps you find a bug where you want to add further helpful information. - Dynamic font selector: I also don’t know for sure, what exactly you are missing. Is it the same as in your post from Dec. 16, 2022? Otherwise, could you explain a bit further, please?
- Spending donations: Only a member of the GIMP core team is probably able to answer questions about received donations and their use. I could not find much information on their website, but again - if somebody from the GIMP team is here, it would perhaps be a good idea to report annually about this. IMHO donors have a right to know this.
I hope, this helps.
