BuddyPress Activity Plus

Dear Assistance,

BuddyPress Activity Plus is not working very properly.

The button "Post Update" must be shown only when a member write a sentence.

Fow example when one upload a video that button is useless and has no function so create only confusion with the real necessary button called "Add Video".

Please look at picture enclosed:

I look forward to your reply.

Regards,
Simone
