Scroll synchronization between editor and preview panes in Full-Document rendering mode

[danielfernandez]

The new "Full-Document" rendering mode is great, but can produce strange results when synchronizing scrolling for the editor and preview panes.

Currently, when the editor is positioned at a specific point in the document -let's say, 34%--, the preview pane scroll is positioned at the exact same position: 34%. But the problem is formatted text in the preview pane doesn't have to take the same amount of vertical space and proportions as text in the editor pane, so many times (most times if text includes tables, lists or so), both windows don't match at all after synchronization.

What I suggest is positioning the preview scroll bar based on text content and not simply using the same value as in the editor pane.

Great job!

Thanks for the feedback!

This issue with percentage-based synchronization is noted in the FAQ, and is a problem that similarly affected MarkdownPad 1 which also used a form of full document synchronization: http://markdownpad.com/faq.html#features-renderingmode

In this regard, high performance mode offers more accurate synchronization, especially when elements with differing vertical footprints are used.

I'll see what I can do to improve this functionality.

Has there been any progress on this? I really prefer the full document mode -- the high-performance mode has the habit of jumping around while scrolling, which is really distracting. But the naive scroll logic in full document mode means it's practically unusable for long documents.
