Show if following sidepanel is overflowing
Until a few days ago the "following channels" sidepanel has also shown channels that are offline, just with a greyed out version of their profile picture. But now that those are not shown anymore, there is no more visual clue on whether there are more channels live that you follow than there are shown on that sidepanel when it is not expanded.
To fix that issue I would propose the follling approach (but I'm also open for other suggestions):
Once there are more channels you follow are live than fit on that list, instead of showing the last one of that list, show a grey "+x" symbol, where x is the number of channels that are live but could not be shown because there is no more space to display them. And when clicking on that "+x" symbol, more channels are displayed in the same way as it would be done by the "show more" button in the expanded view of the sidepanel.
