I have a dual monitor setup so I usually have CTOP running in a separate terminal in the bottom left corner of my setup. It's a good place to glance to see which of my agent sessions are pending instructions / blocked / running. Also a good birds eye view to see which ones are about to run out of context.

One thing that I've been doing a bit of recently - there's a CTOP CLI which lets one my 'supervisor agents' automatically drive prompts into sessions that need unblocking
