Lawnchair VS xournalpp

I would like to use Lawnchair on my Hi Reader Pro, but whenever I set it to use a third party launcher (obviously I haven't tried them all, but I tried 5 or 6 with the same outcome) the "Recent Apps" (Square Button) stops working after a few uses. By that I mean: nothing happens when it's clicked.

You can download it here: https://github.com/LawnchairLauncher/lawnchair

Could you please install Lawnchair Launcher & check if the notification is visible in the long press menu?

And probably the most latest version (but not final release). https://github.com/LawnchairLauncher/lawnchair/releases/tag/v12.1.0-alpha.4

I highly recommend Rnote to anyone on Linux that misses the "hodgepodge" notetaking of apps like OneNote. It works like a dream on touchscreens and drawing tablets, with a surprising amount of configuration under the hood.

Also worth noting is Xournal, an older but similar project: https://xournalpp.github.io/

I've been using Xournalpp[1] for many years, highlighting books as I read them, adding in text/hand drawn annotations in whitespaces if necessary. Unlike other PDF readers/annotators, it saves a separate file, so the original PDF is untouched. It can also export the annotated PDF as a new PDF with highlights and annotations.

Obsidian[2] also has PDF support, where you can open a markdown document side by side with the PDF to take notes as you read. I think it also lets you highlight the PDF itself.

Emacs I think has a similar feature, via plugins/org-mode(?) to the Obsidian setup.

And of course your typical PDF reader probably has support for highlighting PDFs too, but I find them clunky and they save by exporting a PDF, which can be a bit heavy-handed IMO compared to just saving the annotations/highlights as a separate file as Xournalpp does.

Currently, I am trying to build a small open source NLP project for which I first find text on a page and then translate it; see the current project state here: https://github.com/PellelNitram/xournalpp_htr. The purpose of this project is to make handwritten text in Xournal++ searchable for all users.

[Xournal++](https://xournalpp.github.io/) is in my option the best handwritten note-taking software out there, because it has all the coolest features (like LaTeX snippets and shapes) and it's open source too, so make sure to check it out!
