YouTrack/Charisma Users: syntax changing poll

I'd like to organize a little poll as to proposed changes to YouTrack/Charisma query syntax symbols.

If you find
type: "Usability Problem" and :"Usability Problem" queries a bit more intuitive or easy to type then current
type: {Usability Problem} and #{Usability Problem} then please go vote:
Change query syntax: replace { and } with quotes
Change query syntax: replace # with :

Or, maybe you have better suggestions?
