Lemmy Support

Working on desktop here FYI if that makes a difference.

So I notice when im in https://lemmy.ca/c/lemmy_support@lemmy.ml and click search it brings me OUT of that community and wants me to enter in one in the fields, but when i start to type lemmy_support it suggests it so i click on it but it still doesn't seem to register that i want to search support and searches everything (either local/all/subscribed depending which ive got selected)

second is there a way to get a complete list of local communities on a server im in or even some way to sort them by any of the fields at the top? ie https://lemmy.ca/communities/ or https://lemmy.ml/communities the headers all appear clickable for some reason but nothing happens for sorting.

Thanks.
