Why are you suggesting it?

Why?

Because the first thing a new MariaDB User sees when starts using MariaDB is the default IDE: And HeidiSQL can not compete with "MySQL Workbench", one of the best IDEs I know. But SQLyog Community Edition (With GPL-v2, therefore, could even be modified by MariaDB Team), is good enough for basic use, and much better than HeidiSQL.

So I am suggesting it because I see it as a mean for MariaDB promotion: "MariaDB not only is great software but has a great IDE!"

However, I would modify the IDE, and remove the "Update to Enterprise" button that appears at the bottom of it.

MariaDB Team has already forked "Percona XtraBackup", "SQLyog Community Edition" could also be forked based on GPL-v2

Well, maybe you need to speak to SQLyog first, because we are not the ones who remove their Update to Enterprise button.

Otherwise, I think the notion that SQLyog is better, is just an opinion. I did some survey back in the day, and I liked HeidiSQL, as many other people also do. More than free version of SQLYog. I liked dbForge, and Navicat better than SQLyog, too.

https://www.slant.co/topics/53/~best-mysql-client-applications-for-windows

Both surveys like HeidiSQL more. Maybe you can paste survey where "much better" is more obvious.

The point I wanted to reach, more than which IDE is better, is that it would be nice that MariaDB Team maintains its own IDE, just as MySQL team does:

https://www.mysql.com/products/workbench/

In order to offer a complete solution. And this could had been forked from an existing IDE. However, HeidiSQL also works as a basic IDE... Of course.

In conclusion and as a specific action for this issue:

I added the "SQLyog Community Edition" at the end of Graphical and Enhanced Clients MariaDB Knowledge Webpage, to give it to know to other users.

There isn't the interest supporting our own GUI. Community developed versions appear to be supporting MariaDB quite well.
