Hi @Strilanc. A few of us are working on a Quirk-related project as part of QOSF and we're needing to allow for some customization with regards to the UI. Specifically, it is being able to turn off/on whole Toolboxes (e.g. Toolbox_2), individual columns in the toolbox (e.g. Spinning), and displays on individual wires. Before embarking on this work I'd like to know two things:

1. Are you open to the contribution?
2. Can we agree on the approach (I can lay out further details in comments) prior to starting? Ideally, I'll want to match how you might do this yourself.

I'd much prefer working on this with the intention of contributing rather than maintaining a separate fork.
