Click twice on a column header and the autofilter will suggest options, according to the column type:
Options for column resizing
Options for viewing large amounts of data
It is difficult to explain the feeling of the distraction-free mode. The browser collapses and displays the table in full-screen mode, like a Youtube video. Margins can also be reduced.
These options are displayed when the pagination is active (more than 50 records). In full-screen mode, inline dialogs aren't available, so it is not possible to edit the column properties or have autocomplete on formulas. Those options are available in reduced-margins mode.
Formatting is generally done using the Markdown rendering, but the cell background can be changed using F2.
