Clear obvious wrong hints (Unequal, Towers, Keen, ...)

[Hessi9]

A lot of games offer the feature to add all possible hints (numbers,...) to every field - a very usefull option. Unfortunately then a lot of work is required to remove hints that are obvious wrong. I would like to request the feature to remove all obvious wrong hints automatically. This feature is already mentioned at the documentation a.e. at Unequal when pressing the h button. I would suggest make this feature accessable by pressing the "fill all possible hints" button a second time for filtering. This feature would save so much time at a lot of puzzles! By the way I realy realy love this puzzle collection!
