I haven't tried but I imagine the LLM stuff might actually work well for these super-menial coding tasks of porting between related APIs compared to other coding tasks. There are usually a lot of "how do I port this snippet of code from version x.y to (x+1).y" on Q&A sites, forums, mailing lists etc. which is probably in the training data.

I love the solvespace ui, yes it's weird and different but it works well and is internally consistent, except when a gtk dialog jumps out at you, that is jarring and breaks the flow.

I guess my point is. the obviously gtk bits of solvespace are it's worst parts, if I were a better ui programmer one of my goals would be to get rid of all the modal windows in solvespace, make them in line and operate like the rest of the native widgets.
