Sure, we are discussing future directions and volume isn’t so far a problem 
getting people willing to do the work is though . While I agree both parts bin and search need work (search is even worse than parts bin in my view) it is well down my list after learning the source to fix bugs and add new features, doing more work on the parts check script and fixing up existing parts. That said, of the two parts bin is easier because non core parts are user changeable (search is possibly a code change or possibly better tags in individual parts either of which are more complex). You can move things around in the parts bins and create new bins for your self with the current code with no code changes needed. If you (or any one else reading) would like to help, that would be an easy place to start. Move stuff around in the bins and add new bins to better arrange the bins and post what does and doesn’t work for you (including what code changes would improve the situation but realizing implementing is likely to take a long time). For core parts, once you have a better arrangement (which you can demonstrate by copying the part in to the mine parts bin then moving it where you want) that can be done by submitting a change to the parts repro on github which is also much easier and more timely than a code change.
