4.3 out of 5
PNG Promblem

png images should have a transparent background

Navigation

No pan or zoom for large charts, unusable.
Cannot open .mmd files

Almost there

This is quite good... however, I can't seem to change my background color to white. If I use the base theme and set the background color, the setting is ignored.

I'd also like the ability to set a zoom factor when exporting images. Other than that, I have absolutely no complaints. It works as advertised, is fast, and seems to be stable.

Fixing those two issues will each earn back a star in the review!

Very helpful today

I was looking to export a number of diagrams at work today, and the combination of a UI based renderer and a terminal utility was a great help. I could tinker with layout and margins and once comfortable, could run through my whole project. Well worth the few dollars for the paid version

Truly an amazing app.
