So the suggestion is in an action like Set/add/remove variable sometimes you just want to change the sprite to another one and keep the same action (for that both objects must have the same variable). Right now to do that you have to click in the action, click 'back', then 'back' again, select the new sprite, click 'next' two times and 'done'.
An easier way would be to right click it and have an option to 'select another object', this option would first check for sprites/etc that have the same variable and would appear a box with the selected objects that match it, you choose one and press 'enter' and/or 'Done'. After that, the action didn't change, just changed to another object.
Trust me.. this will make the development of a game faster ;)
