Hitting enter creating error; and loading gif

Hi all

Loving your support and the Buddypress. I have only two bugbears now to do with the Activity Plus module. These are

1) When I enter a URL to upload (video or link), if I hit enter afterwards instead of embedding the URL it returns an error. Instead I have to hit preview and wait. But this is not intuitive and user-friendly.

2) Now when I am waiting for the URL to embed (after hitting preview), there is nothing to show that it is actually embedding. Sometimes this can take a long time and it looks like the website has broken, or not actually done anything at all. It would be really useful to show a loading gif so that the user knows that something is happening.

Please can anyone help me resolve these two issues? I will be eternally grateful!

Thanks

Rob
