Hello,

I got some issues with the activity stream. First of all, I would like to know if it is possible to not show the activity comments as an actual activity like this :

Furthermore, I got a problem when I click on a picture in the activity stream, when there are too much comments, they disappear to the bottom right of the screen :

Finally, I have a problem with permalinks.
When I set permalinks to anything but the default, if I click on “activity” on a member profile page, it shows site/user/activity, but redirects me to site/activity, and the same for every other sections (like site/user/forum to site/forum)
How can I solve that?

Thanks for reading,
Best regards
