Problem

Composite timeout was incorrectly being saved in the settings.json file as str.

Impact:

If a user had changed the composite timeout setting:

• They could no longer open plugin level settings.
• From next launch, the thumbnail action would not display.

Resolution:

• Don't type all settings values as str
• Don't type composite_timeout values as str
• Load current saved values for composite_timeout as int to enable loading of broken settings
