Thanks for your interest in LoopBuddy
LoopBuddy will work if your theme supports the Loop Standard. If it doesn't, it can be modified to use it. However this type of modification is beyond the scope of our support. Depending on your theme we may have some documentation to steer you in the right direction.
You should be able to use LoopBuddy in a widget area regardless of your theme.
Here's a link to our full LoopBuddy Codex with detailed information.
I hope this helps. Please let us know if you have any other questions!
Thanks,
Gerroald
