This might be possible (even simple) to do this in avy already, but have you 1) considered allowing hints for general text objects like inside and around parentheses, in or around strings sexps and so on?

Would also be neat if you 2) could combine an action with a text-object and then pop the mark afterwards in one keycombo like Eno does: https://github.com/enoson/eno.el

I starred eno because it seems like a good idea, but I really do not want to use many different "jumpers".
