The torrents with names:
[Chihiro] Grisaia no Kajitsu - 02 [1080P Hi10P AAC][B3F5FC2D].mkv
[Chihiro] Grisaia no Kajitsu - 02 [720P Hi10P AAC][7BA11094].mkv
[Chihiro] Grisaia no Kajitsu - 01 [1080P Hi10P AAC][09C3203D].mkv
are not marked with their respective resolutions (720p or 1080p).
This makes it hard to follow just the 720p variant, for example.
[Chihiro] Grisaia no Kajitsu - 01 [720p Hi10P AAC][BAA4257A].mkv is on the exact same form and is marked with 720p, I suspect this is due to the 'P' is lower-case here and upper-case for the other torrents.
I suggest that also "720P" and "1080P" are recognized as standing for "720p" and "1080p" respectively.
