- Hotkeys can now use any character, and modifier keys are not required. - Refactored the colors of the topbar, searchbox, toolbox, and widgets for consistency. - Toolbox/interval refactoring and simplification. - Histograms now show up in the legend, and will use shorthand notation by default (e.g 34k rather than 34000).
