Hi
I'm using an opensource program called draw.io. ( https://www.draw.io/ )
It has some limitations, which I need corrected if possible. It seems plugins can be created, so this might be the way to go.
Firstly, I need to be able to create links with html code eg. 'google.com class="myclasshere" target="myframe"' etc.
There will also, be some minor things (i think it's minor), that I want to be possible.
Send me PM for details, and I'll explain in details, send you some files to look at. Let's discuss payment / amount after the project is clear and understood.
Regards
Casper
