Thanks for the redesign!
here are some corrections for the new eq:

1. the shadow of the button stay always visible (doesn't disappear) and add more space between the button and the title
   

2.1 "snap bands" wasn't easy to translate in some langs, so some (like in german) add a longer explanation to the title, when reaching the left edge the text is out of the screen - seems a correct padding (=0) is not defined

2.2 the notice about delete the current setting isn't in full screen with and that's why the text is shorten inside (also in EN), but maybe a notice like "do you want to delete" would be more clear because the notice disappears very fast and the user don't release that he can undo the action here

3. this one is a little bit tricky because when you slide inadvertently between the sliders the whole eq dialog is been closed, happens mostly on the bands when you try to grab them above or below the action field
   

mentioned in issue #929 (closed)

1. fixed

2.1 fixed

2.2 It's the standard padding of the snackbar. As it has the same background as the equalizer, it's not really understandable though. It's probably easier to understand with the light them

3. Not easy to do. If we get more report about that, we'll try to find a way to take care of it.

1. both issues are still visible in the last nightlies
   
2. 1. fixed
      2.the light theme shows the whole snackbar (thanks), the content will be shorten to fit in it, on english (pic above) it's this strange issue with "not inline elements" (not on EN system default) , so this is ok for now.
      
3. the most important area of the not sliding function will be between each band. For the above and below area it's ok not to turn off the closing dialog function but the touch point of each band should be as wide as possible, so we won't have any spaces between the bands because this it actually the area where you slide a lot.
