Adds a timer to Rosiminc's Nono Café with some basic functions.
This is a script that adds a timer to Rosiminc's Nono Café (https://github.com/RosimInc/sg-nonograms). It has the following features:
- Manual controls to start and stop (reset is only possible once the nonogram is reset).
- The timer will start automatically once the nonogram (or the surrounding area) is clicked.
- The timer will stop once the tab is changed or another program is active instead of the browser, and will be resumed once the tab is active again.
- The time for each nonogram will be saved in case you want to return later to it, however it will be erased once the nonogram is reset.
