Instead of the drab blue energy bar colourise it to indicate if player is ready to jump

ie at 25% or more then yellow and green when at 100% for wormy holes...

Should also have a check box in the config area to turn the effect on and off.

+1 but make the color chosable

+1 to both of you.

This is possible with skins i guess, but still a good idea. +1

FlamboyanceHUD may be suitable as a base for GS to start from. Though it doesn't specifically address the suggestion as written it does have a few other HUD coloring features that might be attractive to some.

Similarly, as an interim solution, TheRedSpy or someone else could possibly add the suggested functionality to it or themselves use it as a base.
