> why did you choose against icons? Maybe we can try to match some of the Makefile mapping, e.g. "targets" seem to have a similar meaning.
It's not because of the icons themselves but because there's no clear semantic mapping of the kinds provided by meson and icon names (which are tailored to programming languages) - so I wasn't sure what to use. If you have some suggestions which icons to use for which kinds, no problem to add them.

OK, these can be removed (or mapped to local variables which aren't shown in the sidebar so symbol goto still works for them).
