Option to show all Threads - even non-subscribed

I'd like to propose a feature request for Threads. A profile option to show all threads under each channel, even non-subscribed with read/un-read indicator just like for normal channels. 

Currently you have to search each channel individually and subscribe to each thread, in order to permanently see them in the channel overview on the left side. That's not a good solution because threads come and go and you'd have to skim through each channel repeatedly to find new threads. 

Another possible solution would be an Auto-Thread subscribe that joins every new thread automatically. This feature has already been proposed here and there are probably bots for it as well since you auto join a channel upon ping.
