One minor nuance that I've noticed is that when both the previous/next links are disabled (e.g. no other pages), the styling isn't very intuitive. I found myself clicking the links and resultantly began to suspect that something was functionally wrong. I understand that you've used lighter colors to imply that the links are disabled but it's ultimately confusing.
- For the condition when one of these links are disabled, set display to none for the disabled link.
- For the condition that two of these links are disabled, either set display to none or via PHP substitute in a "No other pages" message.
- Alternatively, though less desirable, for either of the above conditions, use much lighter colors for the arrow graphics and text styling and augment the cursor type (the standard cursor implies an expectation of action).
- For the overall design of the arrow graphics, considering the small size of the graphics, the shadow produces a blurry effect. For my own custom designed arrow graphics, I ommited the shadow and it produces a much sharper effect thats consistent with the sorting arrow graphics.
These, of course, are just my opinions but worth sharing no less.
Thank you for the fantastic plugin.
