Anki add-on: Proportionally Adjust or Increase New Card Limits for Today with One Click

This addon adds plus and minus buttons next to your new card counts in the deck browser (home screen). Upon clicking, the new card limits for today only will be adjusted relative to the decks' baseline values (i.e. per-deck setting or preset setting), for that deck and all of its child decks recursively, without touching the baseline values. In this way the relative proportion of new cards from the child decks will be maintained while studying additional new cards. The motivation for the addon is to make it easy and convenient to study more new cards than scheduled that day without having to go through lots of menus or getting an undesired blend of new cards. Notes Preexisting "new card limit for today only" values are ignored and replaced. The addon does not modify any aspect of the database other than the "new card limit for today only" values. The percentage by which to increment or decrement per click can be adjusted in the configuration. The default is 0.25 (25%). Values cannot be reduced below baseline. You can only learn more, not less. Since scaling is relative, decks set to 0 new cards will remain as such. The addon may not work correctly with addons that modify the deck browser substantially. In this case please consider adjusting the code manually to adapt to your situation. The addon may or may not work with versions older than 25.09. As is common, it may be the case that such functionality has already been implemented in a different addon that I failed to unearth.
