Have Swipe L/R/U/D and Drag L/R/U/D (+/- inversion )have some consensus among users/programmers?

hi,

i used the "swipe back to clock" app which is good,
on ANY app a left swipe will return to the clock,
from the clock i use "pattern launcher" to get to "folder launcher" or apps.
And get back to the clock again using it.

however,
in sci calcultor,
this got 3 panel for keyboard,
it used a left swipe/right swipe to choose keyboard, and leaving swipe U/D to be non-functional

1. thus i think if i have time later, i'll try modify the "swipe back to clock" to use swipe U/D 1st,
   then ADD this function to the app, with the ability to use the apps' list (always on, always off, white list, black list) etc. This approach i think is easier to me.
   
   

then I used music control,
it use Lt swipe for prev song, Rt swipe for next song, Up swipe for vol up, Dn swipe for vol dn,
which completely beat me.

1. I'll suggest let's reserve swipe (swipe is easier to program than drag, in bangle i think) for APP management more,
   and drag for things within the app. e.g. for this music control app, a Dn swipe to close it/back to clock (as in windows 10), while the drag L/R/U/D for prev, next, vol up, vol dn etc.
   
   

later i read the posts and found that some people have different meaning on up swipe, which is other people's dn swipe (inversion). would be good to consider that too.

thanks.

ps: I found this have a higher priority than the screen lock issue, so i'll work on this first.
