Tables on the RTD site do not have text wrapping enabled, so there is often a lot of horizontal scrolling involved in reading them, especially for rows with very long descriptions (like the --template-resampling-grid parameter on the Usage page). It's easy to enable text wrapping in the tables, per this set of instructions. I can make the changes and open a PR if this is worth implementing.
On a related note, would it be worth it to use sphinx.ext.linkcode to link the documentation to GitHub instead of local snapshots of the code?
