I'm very happy with this app

It works great, and it is bug free.
iWriter Pro is my favorite Mermaid live editor.
Developer support is awesome, my feature requests and bug reports are heard!

Would be great, with some improvements

I had to let my previous markup app go, b/c I moved up to macOS Catalina, which is 64 bit. There are 3 problems with this app that slow down my productivity. 1) I need an app that recognizes URL syntax, and automatically makes it clickable in documents. 2) Every time I open 1Write I am searching for a document to read or edit. However, 1Writer's default is to search the entire computer, rather that the designated file folder of my docs. Having to click the name of that folder after attempting a search is an unnecessary step. It would also be helpful if the app would automatically reveal documents as you type the letters you are searching for (live search). 3) I am often moving from one document to another, and therefore want 1Writer to remain on the screen when I exit a document. It is a pain that every time I exit a document, I have to bring 1Writer up again. There should be an preference option to keep it on the screen in the background while editing a document.
I do think this app can be very useful with these improvements.

Almost what I need

I am searching for a replacement for my ancient markdown editor, without updates for almost 4 years. I think iWriter Pro is the one that I'll settle on.
Why only 4 stars? I can't load images without putting both the file and the image under the iWriter directory and that needn't be under MacOS.
I'm glad no data is collected and I'm super happy about Mermaid support.
But I want my images!
