SG6 Edge+ Theme Questions

[bounce007]

Hi guys, pretty new to the Android world, but long time Mobile Nations Member.

1) In the SG6 Edge Plus theme store, is there no way to search for themes?
2) (Probably a dumb question but....) If I download SG6 themes from independent developers, can they be applied to the SG6 Plus?

Thanks for the help

EDIT: I meant to post this in the SG6 Edge Plus Section... sorry
