make nucleotide selection box floatable

it is time consuming to select a different color each time you want to make a change in the RNA structure. having the color box at a freely desired location other than below, right hand corner may be a good idea.
Then add a button somewhere to restore it to its default location.

Thank you for your input. This is an excellent idea!

We are going to discuss this in the EteRNA developers meeting. I have listed it as a feature #154 in EteRNA Bug/Feature Tracker

While we look into this, you could try using hotkeys for chaging colors. Key 1,2,3,4 corresponds to the four colors in the pallete.

thank you Jeehyung, i was not aware of that, it helps !
