This is a tip I have re-written, still tweaking a bit before posting the code, that I thought you might like. Basically when you or a member posts a status on the activity feed and then other members comment on it the comments can get quite long, also when you click on the comment count you get taken to another page to view the status. Now the problem with that is you then have to click the back button or home tab to get back to where you came from and then scroll back down the activity feed.
So what this tip does is open that status page over the top of the activity feed so you do not leave that page or place in the feed. With regards to the comments list I have let only the Latest comment display in the activity stream to keep it a little cleaner, if the member wants to see all the comments they just click on the link with the comments count in.
I have added a short status comment in my feed so you can see how that looks. I have also added a soundcloud post and a video post so you can see how that would look if a members adds one of those into the activity feed, by the way I have added a lot of demo comments on the video one so you can see how a long list looks of comments.
The other part I added was for the photos, so if you click on a photo in the activity or it's title or it's comment count that will open over the activity feed as well. This is quite nice as again you can view, comment or like a photo without leaving the activity feed.
I have not added this for forums or blogs as those I think are quite important to go directly to those pages but it could be added.
I have tried this on quite a few devices and browsers ( except safari ) and all works a treat. Any way take a look and let me know how it works for you then I will share all the code etc after a bit more of a code tidy up.
