How do I get my cell height to auto adjust?

How do I get my cell height to auto adjust?

I'm evaluating Zoho Sheet as a replacement for Google Spreadsheet.

Using latest version of Safari, and experiencing the same issues in Chrome.

A few bugs/things I can't figure out:
  1. Auto adjusting cell height when importing from Google Docs or creating a new document
  2. Turning off the auto date formatting for X.Y.Z where they are all integers.. (This is extremely important, as our requirements are written as outlines.. "X.Y.Z" corresponds to a requirement ID.. which is then turning into a date)
  3. The Sheet going blank for an annoying amount of time whenever I have to load more than 80 cells vertically. 
  4. The Sheet not extending horizontally past "R"
