from the thread: I'm using spark 2.6.3 and currently the only way I see to create a bookmark is to find the conference in the room browser and right click. The problem is taht on the server I'm on the list of conferences is very long and it takes some time to load and sort through and find it.
Speaking about the Auto-join option. It is possible to do this quickly if one have Conference tab showing enabled, then in this tab one can see all of his bookmarks and set the auto-join option. But, if one is not using Conference tab, then it would still be hard to find a bookmarked room in a huge list and set that option. Maybe another button can be added to a group chat window's toolbar, like "Auto join". This could be a checkbox, which will be automatically checked if you have already set that option on. But i'm not sure if this is worth, as probably not many users will use it.
