Typewriter mode in iOS MMD Composer Build 51

I’ve had a chance to use Build 51 some today and it’s working pretty well for what I do. The issues I have noticed so far all relate to longish (4-5 page) documents and all seem to be affected by the state of the typewriter mode setting. This is all on an iPad Pro. I noticed some of this back in build 47, by the way, so I don’t think much of this is necessarily new to build 51.

  1. With typewriter mode turned on, when I first tap in a document (i.e. before an insertion point is present), the cursor zooms in from the top and always lands somewhere past where I tap. With an external keyboard attached, the cursor pretty consistently ends up 2 lines past where I tap. With the virtual keyboard, it’s usually 7-8 lines past where I tap. If I turn off typewriter mode, then the cursor appears precisely where I tap.
  2. Choosing entries in the TOC menu always correctly scrolls to the header I tap on. The problem: with typewriter mode turned off, tapping outside the TOC menu always scrolls back to where the insertion point is. This problem is solved if I turn typewriter mode back on — tapping outside the TOC menu correctly leaves the document scrolled to the position set after tapping an item in the TOC menu. This is true with and without an external keyboard.
  3. With typewriter mode turned on, extending a text selection by tapping on a selection handle makes the selection jump erratically when you drag the selection down across multiple lines. With typewriter mode turned off, selecting across multiple lines works smoothly.
  4. The preview does in fact scroll in response to an edit, but the edited line doesn’t make it onto the screen in typewriter mode. It seems to be several lines below the bottom of the screen. If I turn off typewriter mode and edit a line at the very top of the screen, the edited line appears in the middle of the preview. So I don’t think this is actually about typewriter mode, it’s about where on the screen the line being edited appears. I did this test in landscape with an external keyboard.

Even with these quirks, I’m finding MMD Composer stable and usable. I can finally create MMD tables easily on my iPad! I also just discovered that if I’m editing an ordered list, tapping on the ordered list icon in the tool bar cleans up the list. Awesome!

    Yeah -- there are several issues related to scrolling and typewriter mode that are on the list to address. The TOC one might be one I had not experienced yet, so I'll include that.

    (Typewriter mode was actually one of the more complicated features to correctly implement. It took several generations of algorithms before it finally got to work properly on the Mac. And iOS is just enough different that most of those algorithms have to be readjusted.... Oh well... ;)

    Thanks again for the feedback!
