Modal highlighting like in most annotator tools

[notuntoward]

This is a useful plugin, but I'm noticing that each highlight takes more clicks or hotkeys than I am used to on other tools, like Acrobat, pdfXchangeEditor, Drawboard, OneNote,...

In those tools, you click a button on a color picking palette once, and then you are in highlighting mode: anything you select with a mouse or a keyboard (implementations vary) gets highlighted in whatever color is currently active on the palette, which is open as long as you're in highlighting mode. If you select already highlighted text, and then click a delete button (various implementations) then that highlighting is removed. But you stay in highlighting mode until you turn it off.

Here's OneNote's palette:

You just click a pen at the top, and then you can highlight with no further clicking required, until you want to delete a highlight, want to change colors (click a pen), or want to stop highlighting, in which case you click it off.
