1. Please follow the sourcery suggestions.
2. Font color and circle size 2.a) Use the same white or black font color depending on the background for the number circle (same as for the time and date). 2.b) Reduce the diameter of the circle a bit.
3. Please explain how this can work for the video component. Is there an API connection?

Right now it seems there is a mix of the previous "browser based" implementation and the current implementation.

1. Anonymous users can still star a session, but it does not reflect the number. Expected is: Just like in the previous eventyay version a pop up should open "Please login to add a session to your personal schedule. - Not now. / Ok."
2. If a logged in user stars a session and then accesses it with another browser the session is correctly starred. But: If a user unstars a session in a browser, the sessions is not unstarred in another browser. Expected: At least after a browser refresh it should show the correct session status.

Sorting does not work at all yet. I also see the option for different timezones. This is out of scope for this issue.

Hi @mariobehling,

Font color and diameter of fav count is updated. And the pop will look like above, do you have any feedback?

1. About the unstar issue, I open 2 browsers, if I unstar one, and refresh other brower, it also reflect the number, could you test again?

2. About sort issue, currently we sort in a list session bucket (all sessions in each 30 minutes), with that way it will not break the layout as current layout showing a list bucket of sessions in 30 minutes.

About the connection with Video.

From Talk:

• when user star a session, if user existed in Video, call api to sync the list favorite sessions to Video for that user. (same when user un star a session)

From video:

• when user star a session, trigger a API to Talk to update list favorite session in talk (same when user unstar a session)
