Description Dirk Wiesenthal univentionstaff 2015-11-05 13:25:42 CET
It took my browser ~10 seconds to load the youtube videos (due to some api calls).

Suddenly, the thumbnails appeared. This looked awkward (if not broken). We should add some kind of spinner until they are loaded.

The details pane is opened when clicking on an App, so one can witness this behaviour easily.

One new feature of the UCS 4.1 App Center is the ability to present thumbnails of multiple screenshots in a gallery/carousel view (cf. attachment 7067 [details]).

The UMC App Center usability should be improved. The app list is getting longer and longer. :)

* Bug #39794: fixed error opening app when it has no gallery
Comment 9 Alexander Kläser univentionstaff 2016-04-12 13:41:02 CEST
Changes: OK, it looks really nice now =) . Videos are loaded on demand and the 
  error handling works fine, as well! I only found a few minor issues that 
  should be fixed in a second go.
YAML file: OK

BTW... when App Center server + youtube is not accessible, the dummy images for screenshots will be scaled down to a height of 0px when clicking on them. But IMHO, this is not really an issue.

iPad mini:
* No scroll button on the left side of the gallery
* Delay of ca. 0.5sec for scrolling to next image when pressing left/right button
IE11:
* YouTube videos are not shown... I tried some configurations, however, did nott
  succeed.
* When scrolling down on the App Center gallery page and clicking on an app, then
  the app detail page will be opened with the window having scrolled down to the
  bottom of the page.

→ I opened Bug 41038 for this.
