It would be ideal to have the ability to be able to change highlighted text to a different colour without using the lasso tool on every single different page where that colour is found. It would also be neat to be able to select a page range to change all of a certain highlight colour to a different colour (Ex, having blue and yellow highlight on multiple pages but now wanting to change the yellow highlight to pink, etc.). Almost the same idea for printing specific pages, you'll be able to select single page, range, or entire document and the highlight colour you want to change or erase for that colour selection/page selection. (As opposed to going through each page and using the lasso tool or erasing manually)
