@acidyo gave me an idea today on the Witness Town Hall on Discord

Can you make the https://dhenz14.github.io/hiveencrypt have filters for HP and if not to hard KE index too. The KE index is sometimes useful, for me at least to understand the message context when/if they come dually encrypted, and avoids me having to go check the user/etc.

Another suggestion would be, to check last transaction from the account, to sort of show "how away" (or present) is a sender after its last communication. Helps with understanding also if either someone is ignoring you (because they have put filters) or if they are just not paying attention to encrypted memos.
