edit changes mirror?

Hi All,
was only wondering - does it exist something like a ‘edit changes mirror’? Have made a character and already applyed mirror modifier (bad for me :spin:). Now would like to make some changes of the model (legs, hands,…etc). Is there some way how to mirror edit changes?
Hope it understandable question :confused:.

thank you in advance

one way is to turn on ‘x-axis mirror’ in ‘Mesh Tools 1’
Another way is to remove one side of the model and add new mirror modifier (of course this only works with a symmetrical model)

great - good idea. thanks
