Your app is ok but syntax markdown is not correct.
Examples: > sometext
This syntax Is a block quote in markdown. Previewing shows just an indentation and not as a typical markdown block quote.
Why is the background of markdown preview “black” in Textastic.
=== is in markdown a horizontal line. In Textastic markdown preview the horizontal line is sticking to left and right margins.
A preview in Workingcopy of that same markdown file shows no horizontal line, instead I see === (yes in preview mode)
How can I create a table?
Of course in SublimeText and Visual Studio Code there are some smart people who create extensions.
I am quite sure both developers of WorkingCopy and Textastic are smart people as well, please check your syntax highlighting otherwise I have to state here your apps are not worth the money. Yes I purchased both apps.
Come on Guys, please check the syntax. I would really appreciate the update. ;-)
