I would like to put various things up on recently tiled areas, and I'm not
sure about final positions, etc., so I don't want to drill and plug.

My last experiences with sticky pads, glues, etc all came to nothing, the
widget either fell off with time, or slid gracelessly down the wall.

But what about now; is there some sort of sticky which is unconditionally
strong, but the fixture can be chipped or pried off without damaging the
surface, I don't care so much about damaging the fitting, so perhaps it
could be broken up a bit, and solvent applied.

I read of very strong jollops here, but are they perhaps _too_ strong and
would wreck the wall : (
