Use it now
Plugin button hotkeys can now be a lowercase letter, not just a digit
What
The hotkey property on the plugin-facing Button component now accepts a single lowercase letter from a to z, in addition to the digits 0 through 9 it already accepted.
Why
This gives plugin authors more available hotkey options for buttons, since digits alone limited them to ten possible shortcuts.
