Currently, the character sheet has a sidebar to the right (which can be moved) that displays detailed information on whatever you have selected. The opposite side (left by default) only has the custom dice roller at the bottom left. 

Some characters have a wide variety of resources that they use often. For example, a Paladin's different attack actions, their Channel Divinity, their spell slots, etc. One that I'm running specifically also has a racial trait that's used pretty heavily. 

I propose an additional, customizable sidebar that you can pin actions and features to. This would be useful to have your various attack actions available at a glance, spell slots and class resource pools, racial trait uses, etc without having to click and scroll through multiple tabs on your character sheet to find and use each one during a turn. Thoughts?

I'd love having something like this. At higher levels, it's so easy to forget I have certain features or items, and I find it even easier to forget when using D&D Beyond vs. a paper character sheet. It would be nice to have the equivalent of a sticky note on the page for things I'm likely to overlook during play.

I like the idea of being able to pin an often used action. That could be very useful.
