improve language swipe cycling

[codokie]

I've added a setting to adjust the sensitivity of the language swipe/slide gesture distance sensitivity.
The current step value does not work well on some devices like S22+.
Here is the current behavior:

High.mp4

And with the new default Medium option selected:

Click to expand

medium.mp4

fixes #255 and #614

Sensitivity 20 is very low for vertical sliding. I am not sure about this approach. Related issue: #255

[RHJihan]

Low sensitivity kind of fixes the flickering problem. However, it requires more travel distance and, so, more time to type. This is a drawback. To address this trade-off, perhaps we could consider other options, like the ones mentioned in #255, such as switching only one language per swipe or stopping the cycle at the end of the enabled language.

This PR is a positive step forward. I'm just curious if there might be an even more optimal solution to this flickering issue.

I'm curious if @nach0 has any thoughts on this approach.

Just some thoughts, haven't read up on the old issues yet. (so some parts below might be outdated)

If sensitivity is too high for swipe to be usable, does it also apply to cursor movement?
My reasoning was that if a user is able to place the cursor with character accuracy, they should be able to to select a language with quarter that accuracy.
If the general sensitivity is too high, maybe the setting could adjust pointerStep instead?

In my opinion a slider is preferable over a bunch of fixed values, because it allows more fine-grained tuning and requires fewer strings, so less work for translators.

[RHJihan]

Should I pursue both solutions?

I am unsure about which approach would be better. Or implementing both will be a good decision? I think it will be better than the current situation. However, I use only two subtypes, I cannot give a final though on this.
But I don't think anyone would be unhappy if one language change per swipe is a tweakable option.

works perfectly. loved it

@Helium314, just wanted to kindly check in on the status of this PR. I know you're busy, but this PR would be a huge update for me. I’d really appreciate it if it could be reviewed when you have a moment. Thank you!

Closed due to @Helium314 unwillingness to work with me.
