Made this plugin to calculate RC filters and parallel resistance. Just been published to the Chrome store:

You lock one of RCF and you adjust the other two while the calculation updates in realtime. You can cycle through E12 values with the up and down keys.

The parallel resistance calculator keeps adding more resistors as you enter values

Maybe some of you guys will find it useful. Spent quite a bit of time on the UX to make it painless

I'm surprised they accepted my unhinged screenshots

I would love to do a plugin like this. I have an Excel sheet that I set up to do around 10 different calculations for pedal stuff. Works great, but it's not pretty like yours.
