Wanted Feature/fixes

[Frozen-Fang]

1.Would like the ability to make the gallery the width of the screen so sidegaps are removed

2.Ability to hide of move arrows in gallery they currently cover the image

3.ability to hide some options from ultra-galleries (example: I don't use the remove or Full or download under single image options at all) they just make the page bloated, and they increase the margin size cause they stack on mobile
