Apple Pencil Inking Improvements — line width and eraser
First, thank you for implementing this, it brought me back to reading in Zotero, and I love it! I have some small requests to improve usability:
1) Adding erase functionality — right now I can only erased by hitting undo or by selecting an annotation and selecting delete. It would be great if there were a mode that could be activated by the pencil double tap like in other apps that deletes an annotation when you tap on it (fine-grained erasing would be great too, but even this small erase functionality would be great)
2) Adding size options for the line thickness — when I zoom in and mark up a figure, the pencil width is too thick right now.

P.S. Thanks for adding the ink option. I love it.
Also +1 for the feature request for more sombre colours like blue and black, as in this post: https://forums.zotero.org/discussion/92657/ios-beta-159-with-apple-pencil
I've now moved back to reading PDFs directly in the Zotero pdf reader on my iPad since you've added the pencil feature - big thanks for it!
Love using Zotero on iPad w. pencil, btw.
Minor related suggestion, take it for what it's worth: I mostly use the smaller line widths, but they're finicky to change between (sizes 0.8-2). One solution could be making linewidth increase somewhat exponentially with the slider. For example, size=sliderpos^2.5/125 would give the same range as before but would give more room to adjust in the smaller ranges. It'd sacrifice precision in the larger ranges, but I'm guessing that pixel-size precision isn't so important there.
An additional suggestion:
include the ability to add "page area" to the margins of the PDF to make room for writing more in-depth comments. Many papers the margins are too small to properly write down serious annotations.
I make a lot of errors while writing halfway through a word and usually only need to erase one letter or half a letter sometimes.
Double tap is a gesture that switches between the active tool and the eraser. See the bottom of this link: https://support.apple.com/en-us/HT211774
I also love yotamat's suggestion: "include the ability to add "page area" to the margins of the PDF to make room for writing more in-depth comments."
Edit - duh - under the colours!
