Lots of schools have Smartboards, but the software is very bloated and doesn't run well on low-spec class computers:
It's also very expensive.
If you don't need any of the extra features, and just want to write on the board, the Openboard runs much better.
Openboard is also useful for video conferencing and educational screen capture videos.
It would be great for people to be able to run Openboard without having to install it.
I 2nd the request to portablize the open source Openboard https://www.openboard.ch/index.en.html
Please Consider! Electronic whiteboard software is way too expensive.
Here are the details on the settings files and locations: https://github.com/OpenBoard-org/OpenBoard/wiki/Settings
Sometimes, the impossible can become possible, if you're awesome!
The program used to be called Open Sankoré but was forked. Here are two threads here on the site about that program: https://portableapps.com/node/54362 and https://portableapps.com/node/37146

Also thanks if you're a teacher for your service during these hard times.
In Covid times it will be great to have for tutors.
