Xournal++ has this feature where, even if if you're in their equivalent of "Select With a Rectangle" or "Select With a Polygon" mode, if you tap (without dragging) on a stroke or image, it will select it like a 'one-shot' "Select One by One" mode.

This makes using a stylus more much ergonomic, as you will be able to select long lines or large images easily in "Select With a Polygon" or "Select With a Rectangle" mode, especially if there are foreground strokes that you do not want to select. Basically the benefits of "Select One by One", but more easily accessible.

I've done a poor attempt of showing it from a screen recording, a video showing the stylus input would have been more appropriate.

No

Describe the solution you'd like
Tapping on a stroke or image whilst in "Select With a Polygon" or "Select With a Rectangle" mode will act like a one-shot "Select One by One".

Exact implementation may differ, but personally, I would prefer it to allow only one item to be selected. That is, if multiple strokes/images are tapped, the previous selection is cleared. This is subjective though, some people may prefer it to work like "Select One by One"

Describe alternatives you've considered
I suppose "Select Intersecting Path" is a possible trade off. I still see myself using "Select With a Polygon" as I wouldn't miss small dashes
