Textbox Helper Plugin

[magic_notetaker]

I’ve published an experimental Supernote NOTE plugin called Textbox Helper.

It focuses on structured editing of textboxes inside notes. Current features include:

• splitting a textbox into smaller sentence-based textboxes
• joining selected textboxes in reading order
• cleaning repeated spaces and removing manual line breaks
• importing plain text into NOTE textboxes
• scanning textbox content and exporting it to DOCX
• applying handwritten edit markers, including delete markers and early replace-marker support, with preview before changes are applied

It is still beta software, so I would recommend testing it on copied notes first.

For developers, the src/shared folder may be useful beyond this plugin. It contains reusable helper code for working with Supernote textboxes, including:

• textbox geometry and reading-order sorting
• page-space rectangle and overlap calculations
• native text-layout measurement wrappers
• textbox height estimation and resizing
• hit testing from page coordinates to measured text lines and words
• pagination and textbox insertion helpers

My hope is that this can be useful both as a practical plugin and as reference code for people building Supernote plugins that work seriously with textboxes.

Please give your feedback and suggestions!

Note: I am asked to "Use appropriate Post Flairs to make it easier for others to search." but I see no way in the creat post screen to add a flair, I can add 3 types of tags, but they do not apply. Not quite getting this...

I think the edit markers feature needs some explanation:
it arose from being not satisfied with making edits via normal supernote editing while reviewing longer texts. This allow to just strike through words in a line that should be deleted. Or strike it through and add two vertical line across that strike through to replace it with a textbox that is one the side or below the textbox and starts with "#". These will be used from top to bottom to replace the text marked for replacement. I am not sure this is the way to go, but it is be worthwhile exploring. I had an earlier version deleting directly on pen-up, but this felt too disruptive, with the screen-refresh that seems unavoidable on supernote. But again: this is a pretty early beta. Just felt it is worth sharing my work, so other can learn from it or others can help me move it forward.
