What does the flag/pixelated flag/flag with stars button do?

Ah, the difference is hardly noticeable at my screen's resolution.
I must say I'm not a fan of clones. While figuring out the layout of a level is fun, actually solving them is tedious and frustrating. Spending 20 minutes zooming in and out trying to count all of the adjacent mines only to discover that there is not enough information to proceed without guessing is not fun. And that's even if you get to this point — not having all of the adjacent cells visible at the same time makes making a mistake while counting much likelier.
The ones like 13 and 15 where you can see the entirety of the level are not that bad, but 14 and 16 are the absolute hell.
You should consider making the game generate levels guaranteed to be solvable, like e.g. Simon Tatham's version or 14 Minesweeper Variants do. That would let you avoid hand placing safe zones and lowering down mine counts. SGT's version is MIT licensed and the algorithm should not be hard to adapt as your version doesn't alter minesweeper's rules.
Another feature I would love to see lifted is putting the "chord" action on left click. Left clicking opened cell doesn't do anything anyway. 14 Minesweeper Variants in addition makes it perform the complement action: when there are only as many unmarked cells as there are unmarked mines, it marks them all as mines.
Another feature that I think would make later levels less frustrating is to make completed numbers (i.e. with no adjacent unmarked cells and with # of adjacent marked cells matching the number) desaturated.
Oof, the code related to generating guaranteed boards in SGT's version is about 1500 lines long, it's almost as many as this game's entire codebase (excluding header files). Also the code is quite hard to understand at least for me, with all the bit fiddling and set and perturbation stuff. Don't think I have the ability to add this. Feel free to PR if you are able to figure this out though
