[enhancement] better indication of when there's not enough XM to perform an action
ok ok, hear me out.
i'm mentoring my 77 year old mother. she loves it, but there is some cognitive decline, so bear with me.
in cases where there is not enough XM in the tank to perform an action, like hack a portal, the button is dim ("greyed out" if it were grey), but there is no real obvious indication that the REASON you can't do the thing is a lack of XM.
it would be better, i think, to NOT grey out the button, but to make the button give an OBVIOUS (high contrast color) toast message (on the screen for a sufficient amount of time to actually read (see my other bug posts)) indicating that the problem is a low XM tank.
