"title": "Great tool, though not clear what version of Mermaid it supports",
"body": "This is exactly the kind of tool I was looking for that allows me to write diagrams with my text editor of choice with all its features and shortcuts that I'm used to, and see the diagram rendered immediately on saving the file. It also has some nice export options for the rendered diagrams. Overall, worth the 9 bucks for the full version. My only issue so far is that it does not specify anywhere what version of the Mermaid standard it supports. The help and FAQ link to the official Mermaid site for reference on Mermaid syntax which implies it should support everything documented there, but I have noticed it doesn't support newer features such as central connections and half arrows on sequence diagrams, and it also does not support combining aliases with participant type configuration on sequence diagrams either. It would be useful if the Mermaid version the app supports was listed somewhere (such as the FAQ or Release Notes), to make it clear what features should be expected to be supported.",

"title": "Intuitive and Geared for Success",
"body": "I am pretty jazzed. I have been wanting an app like this because Mermaid is a very handy, portable, and powerful way to visually show how something should work, be in time, perform, and flow. The challenge, similar to markdown itself, is learning the syntax. This app helps you with this by providing templates that you can start with and direct links to documentation where a specific detail is needed. For someone exploring Mermaid, these features built in to the foundation of this app are valuable. I have already learned several new things thanks to this feature. The UI is clean and easy to use. For the price it is a no brainer to get.",

The app is easy to use, with a clean and clear user interface, and plenty of templates and custom capabilities. Recommended.",

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!",
