The highlight color make words can't be saw clearly;

highlighter tool should not work on texts or black color shapes. highlighter is for emphasising text but currently it changes text color along background color which makes it difficult to read. I suggest highlighter not affect text and only change background color.

Text doesn't stay dark and clear after adding highlight

When you highlight text or handwriting, the text underneath the highlighting should stay dark and clear — but Papyrus makes the underlying text hard to read when you add highlighting, same problem with Samsung S Note, the following two apps did a better job with their highlighters, Goodnotes on iOS and Note Anytime on Android

1. Goodnotes (both handwriting and text stay dark and clear after adding highlighting)

2. Note Anytime (Just handwriting stays dark and clear after adding highlighting, not the text, but still, better than nothing)
