Xournal++ is my goto Note Taker when I am scratching out ideas.
I use to do this on Paper but as we all know, bits of paper get lost and hard to find.
Even then, it’s hard to know where they’ve got to.
So with Xournal++ you can save the files as a PDF or any kind of image type.
You can even annotate existing PDFS or images etc, making it a great little tool.
It’s Free and one of many resources I’ll be talking about.
Get Xournel++.
It’s FREE and runs on Windows, MAC-OS and Linux.

It works great with a USB Pen Tablet.
