Hey stray, thank you for the kind words!
Yes, there is a way to darken the textbox whites. You may check the Adaptive mode in Options > Settings and they become a shade of the bg color.
There is no way to create a default element index, but your custom element collection template should appear in the order you created them (excluding the default Name and Category).
And yeah, don't hesitate to ask for features, I try to develop Nebulous whenever I have the time!
