IgnoreThumb Improvements

[derks]

I am having issues with single clicks being mistaken for double clicks based when my 'pointing' finger is still touching the pad. For example, when moving the cursor quickly to a target, and then clicking it... I am getting about 50% single click, and 50% double click. I may be able to tweak this with the FingerHigh/FingerLow options, but I think this could be more precise.

My usage is as follows:

• I disable all 'tapping' functionality
• I guide the cursor with my index or middle finger
• I single and double click with my thumb
• I two finger click with my index/middle fingers together

The trouble I'm having is that my thumb/index finger together are being mistaken for a two finger click, as well as a two finger scroll. I tried the patch from Pull Request #38, however I don't think that this helps me at all. For my use case:

• I want to 'IgnoreThumb' while moving the cursor... because it tends to linger around the trackpad... I can also accomplish this with the 'BottomEdge' setting. However...
• I do not want to ignore the thumb on click, because I single/double click with it

I think the following would be good improvements:

• Differentiate between IgnoreThumb on click vs IgnoreThumb touching the track pad as they are entirely different
• Provide an option to specify the distance between fingers for two/three finger gestures. Meaning... When I two finger click with my index/middle fingers... there is very little distance. If I could set that option, the my thumb and index together would no longer be mistaken for a two finger gesture because the distance is further apart (atleast where clicking is concerned).

I hope this all makes sense... Please let me know if I can clarify anything, or if you have any suggestions to my issues.

Thanks!

As a followup, using the BottomEdge setting is helpful... however only for keeping my thumb/index from trigging a two finger gesture together. On the flip side... doing a two finger scroll (bottom up) now doesn't work so well.

Provide an option to specify the distance between fingers for two/three finger gestures.

I think this suggestion of @derks's is a good one. I'm always accidentally engaging a two-finger scroll action when my thumb is idly resting at the bottom of the track pad.

I'm using a late 2012 MacBook Pro. My two scrolling fingers are generally right next to each other when scrolling, but I have a constant problem where a scroll is accidentally initiated when I'm trying to click with my index finger because of a subtle touch of my thumb. I'd say if the two touches are further than 20% of the trackpad apart, they shouldn't trigger as a scroll. So +1 to the suggestion.
