+- <matrix> element gains options min_rows and min_columns, and the details of fixed_width="true" have been improved
- Fixed: <valueslot>s were quirky with respect to showing as invalid
- Fix a hang-on-exit issue
- Add R function rk.set.plugin.status() to allow further customization of loaded plugins (hiding of individual menu entries)
