Oh, what a honour, a post only for me

1) My "management" is to save a screenshot of every game I finished (only sub-5 in beg and sub-31 in int, all games in exp and gen). So, it's easy to keep track of the times.
2) Not for nonosweeper. There is such a software for minesweeper.
3) I already save them as PNG, as, in my eyes, it's the best format. I use Microsoft Photo Editor, a tool included in the MS Office package, but several freeware (e.g. IrfanView) allows to save a picture in PNG format as well.
4) Unfortunately, I don't have a video. I haven't recorded for several weeks. But it's a good hint. Maybe I should try to do some low 20 with my new nf strategy [nf=non-flagging, a well-known minesweeping abbreviation].
It must have been about 20-22 left clicks. I remember, that due to the 1-1-6 pattern in the rightmost column, I could solve the 1 row and the 3 row with only one click each. The rest was mostly solved click by click.
