Unless an option is added to quickly identify ‘stubs’ like this and delete them it’s impossible to keep them in check…
Some kind of similarity groupings and group deletions would be useful even one click deletion on chat.
I assume the 3 click delete on each chat is so people don’t accidently delete their virtual friends…?
This is another thing… There seems to be at least dual purpose here on the same interface… Some having virtual friends and others working on their subscription… You need multiple accounts to do both I guess?
This conflates memory usage without more management options.
I cleared my chat history days ago but already I have 30 stubs+/day to slowly go through deleting 
. Once a ‘Temporary’ chat is started I see no way of making it save to history again so it’s not a decision you can make if it works…
