i have recently been given the option to pin my three favourite streamers to the top of the list. i believe this is a trial to be rolled out to everyone. i have encountered a few issues.
1. pinned streamers are removed from the list when they go offline.
2. if i move my mouse to my second monitor the box remains open for pinning a streamer thus obscuring part of the stream i am watching.
3. once i have pinned three there is the option still to pin a streamer, replacing one that is already in the list.
both numbers 1 and 2 are an annoyance. number 3 is un-necessary. the option to pin another streamer only need to be there if the list isn't full. it is easy enough to unpin a stream to pin another. the box which appears when you hover over a streamer doesn't need to persist as long as it does once you move the cursor away, and it needs to be able to recognise when the cursor is no longer on that screen so the box isn't left there permanently. pinned streams need to remain pinned, even if they are offline, otherwise there is no point to it as most people watching multiple streamer have them opened on separate tabs.
