A suggestion for the runescape NIS

I just used my bank for the first time since the implementation of the NIS. I keep m y windows mostly transparent, so I can see what’s going on behind them, but I noticed it affects the bank interface as well.

The bank interface was so transparent, I could barely see it. While “permanent” boxes (That you can’t get rid of) should probably be affected by the transparency setting, I don’t think temporary pop up ones like the bank should be – if I want to see what’s going on behind my bank, I can just close the box and look. I keep the others so transparent (about 80%) because I can’t get rid of them. Is that something that can be taken into consideration?
