I have discovered a few issues when i use slide in plug in in mobile
1º in desktep i've been making some test and works really well
2º these are the issues in mobile:
2.1 when i scroll the page the slide scroll with the page instead of staying at the bottom
2.2 when you tap the diferent options in the slide they works but they don't make any noise, and looks like they dont work( usability fail)
2.3 i've testing in diferent themes and according to what i put inside the slide in widget it doesn't work properly. per example with youtube plugin inside the slide, the page doesn't scroll.
2.4 with youtube inside is not posible to see the link to twiter
these are some of the issues i tested, i hope it will help in order to improve the pluin in mobile device.
