Well, I just tried to run one of their on-line demos and was greeted by a message from the past:

   Unsupported browser

   Please install the latest version of one
   of the following browsers to continue.

   Google Chrome, Microsoft Edge, Vivaldi, Opera

"This site best viewed in Internet Explorer" is dead, long live "This site only works on the Blink engine".

Well, ghee, thanks, but I'll just go somewhere else then shall I? While I do have Vivaldi and Chromium installed I only use these to test sites, not for general-purpose browsing. Here's to hoping Mozilla either gets inspired and kicks out 75% of its administrative staff to concentrate on their actual mission or some of those developers decide to be inspired by their forefathers who started the Phoenix->Firebird->Firefox project to get rid of all that legacy cruft. Make Mozilla Great Again!

And on the Web it is a classical example of "Works only on Chrome", oh well.

It works on the latest version of any Chromium-based browser such as Chrome, Vivaldi, Opera, Edge, etc.

All of these are just skins over Google's code.

Does even Microsoft make any meaningful contribution to Chromium?

They do. Microsoft people were largely responsible for the improved default focus ring and input elements. There have been other notable contributions.

Chromium is Chrome with another book cover.

Aren't you the original developer of Gravit? I am wondering what happened to this awesome project. Did you sell it to Corel?

Gravit project was started by a different person (Alexander Adam), it is now owned and developed by Corel.

Thanks. I saw that you posted about Gravit in the past, so I was curious. Good luck with your project.

Can confirm Boxy is well worth its minuscule price. It’s also very fast.

Some of the operations are unbearably slow if images become more complex. It seems to be using paper.js, which works but is not really famous for high performance with complex paths.
