[LH3243] No "gap" element in "customize toolbar" dialogue

System specs:
Scrivener v. 2.9.0.10
Windows 10

Current behavior:
When customizing the toolbar one can add buttons and separators, but not gaps.

Suggested behavior:
A < G A P > element is available alongside the < S E P A R A T O R > element at the “available toolbar actions” box.

Thanks, this has been filed and should be fixed for the next update.
