Slider Fine Tune

in the current floating point slider, it increments, in most cases, by two. that's normally just fine. but, there are times when i'd like to be able to move the slider by a tenth or even a hundredth, without having to write it in by hand. so, what i'm asking for isnt in the remapping of the slider control, but something that would allow a finer tuning when using the thing. i'm not really sure what would be the best way to implement this... maybe a double slide in parallel, horizontal, with the top one being the main slide and the one directly underneath fine tuning whatever the value is in the top one. something like that, maybe.

well, i'm sure there's a ton of ways to do it. you could even put mini switches on the thing to turn on or off the various increments and in that way only have one actual slide. your way would work also and keep 'clutter' off the gui but i'm not a big fan of 17,000 shortcut keys that you have to memorize like in photoshop. i much prefer visual things to things i have to keep in my head
