Here are my suggestions:
A)
Mouse meter - From my point of view, it is the most important missing feature because it allows to set short path strategies for Exp and Gen. Without it is really tricky to say if i'm using the right strategy.
B)
Blue click as a single action event
(press only) instead of double action
(press and release). The idea is to make it faster, saving at least 0.10s.
C)
Hide gridlines option, because gridlines are useless in little T/custom boards and i might be interested to play Exp or Gen without them!!!!!!
D) Statistics window should also include
misflagged squares (for failures),
mines didn't flagged (for succeded games) and eventualy an indication that
BLUE CLICK was performed.
E)
Display exact time in high score tables. F)
EXACT TIME UPLODING FOR CLASSIC LEVELS. 1s is always 1s, however there is a big difference between 1.27s and 1.89s, but the rule "the last to upload a certain score the first" means that 1.89s will get a better rank (if uploaded after 1.27s). What else can be more depressing!!!!!!!!!!!!!!!!!
Exact time uploading it's a matter of fairness and competitiviness. G) Sometimes i wonder myself
"how exact is exact time" or
"why apparently some hundreds of second aren't allowed". In my NONO adventure i have never managed scores like xx.99s, xx.88s, xx.66s, xx.13s, xx.02s and many others ....
WHY IS THAT SO? Is it intentional?really annoying.......
Comments:
Screenshot option: should allow various types of formats including PNG, the best of all.
Nikolaj's 5th suggestion: I like this one, it should be possible to store desired coordinates for each classic level plus the coordinates of the last game played!
