Looks very interesting, but seems to be excruciatingly slow at indexing Python projects. Ran it on https://github.com/fonttools/fonttools/tree/master/Lib/fontT... (~230 files) and it took 45 minutes while keeping all 16 cores of my Ryzen 1700 at full load, sometimes using ~16 GB of RAM. Exiting the application ends in a SEGV, but seemingly without consequences? Also, after moving the database files to a different folder and renaming the "source group", it now asks me run re-index everything. AAAARRRGHHH.
