Import and Export features help backup and migrate configurations, using .dat file.
The file will contain all presets and settings, such that you can take your Light Brush environment to another machine.
You may also choose to use separate configurations for different kinds of work. Then just backup your settings with Export and use them interchangeably using Import.

Reset All Settings
Help->Reset All Settings
Using this feature will reset everything about the program.
If issues occur after reset - you may try clearing browser's cache. (first make sure Light Brush is closed, then clear cache, then open it again)

Exiting program
please use dedicated Exit button or File->Exit, as this helps the program to tidy up before closing.

Notes:
Pen pressure may be limited on some systems due to dropped in-browser/engine support for older OS standards. But perhaps there are workarounds.

All settings (including presets) are stored in browser's cache. Use Import / Export features to migrate configuration.
