Texturing weight values above 1

To be able to adjust the weight of an image for texturing is great.
However, I would find it more intuitive to set the value af a good image higher instead of lowering the bad ones.
Simply because IF there is a problem chances are that there are more bad ones than good ones and it might get a little tiring to find all the bad ones - neve mind the fact that lowering many others will screw up results in other areas…
Right now, it is only possible to lower the values.

My request: Allow higher values than 1!

Ok, I can lower the weight for all other images and keep the good ones at 1, but still…
