Feature Request: Personal Muted words/phrases list

Hi all,

There are times when I would wish to prevent myself from seeing certain words or phrases in chat.  I would like there to be a personal list to which I could add words or phrases in my account settings.  I could then choose to apply that list to all servers I am in, or maybe even certain ones.

This would then automatically hide any line of chat in any of the servers of which I am a member which contained the word or phrase which I have added to that list.  If I chose to unmute those words or phrases, the lines would reappear.

I understand that there are bots which would perform this function, but as far as I know, those bots curate the lines of text on the server itself and delete actual text rather than just hide it, not to mention all server members would see the effects of that. 

This feature would just be for my eyes.  It would be 100% client-side and would not affect what anyone else saw.

Thank you very much for your consideration!
