Haven't checked in for a while, things are looking great!
I'm still finding it a bit awkward to search for passives. When I'm working on a design I tend to search for all my passives in one go, where I apply filters for package, tolerance, voltage rating, etc. then just change the value filter for each part. For that it would be a huge time saver to have a dropdown with standard values, e.g. E24 values for resistors.
I think that in combination with @tomacorp's suggestions for supporting units (e.g. '10k') and only having to fill in a single entry for searching a single value would make searching for passives a lot nicer.
