Hi, The navigation bar permits to navigate within a results set; it contains the page number selector, the begin/previous/next/end arrows, etc.
Reading [0], I noticed that there is much room for improvement. Based on this feature request, here are my recommendations:
1. Remove the "Headers every __ rows" dialog; it's too prominent, is not often changed and is configurable via normal config and user prefs
2. Change the default number of rows from 30 to 25 (related to the next suggestion)
3. Replace the input field in "Number of rows" with a dropdown containing preset values 25/50/100/250/500. Selecting a value would immediately have an effect. I never felt the need to display, say, 37 rows in a page. This flexibility harms usability.
4. Remove the "Show" button and the Start row dialog. I rarely have to change the starting row value. Arrows and page selectors are sufficient to navigate (not mentionning Search).
Comments are more than welcome.
