It would be handy if penultimate had a ruler function, like the iOS 9.3 Notes application has. I use an iPad Pro and Pencil for my productivity and so many times do I want a straight line where free-handing it won't suffice.
I too hate this glitch. It's so frustrating when you've got a lot of notes and it removes large chunks of whole letters. I'm seriously thinking of moving to another note taking ecosystem
