Hello Ole,
I can confirm the same issue here: iPad 2 with iOS 7.1.2 and as soon as I touch a folding triangle Editorial keeps crashing right after launch. As I'm new to Editorial, but a loyal Pythonista user I'd like to switch over to Editorial form my current Markdown editor. Appreciating any feedback, thanks in advance.
Also removing Editorial from memory starts the crash loop.
Best regards from Bavaria,
Armin
Update
PS: Ok, just found out that Editorial keeps scrolling if I try to mark anything of use the text selection function. With and without the Logitech bluetooth keyboard the input cursor jumps out of view after I start typing. If you need more information, feel free to contact me.
