Many thanks for your plugin and your efforts :)
For a long time now i have been wanting a plugin like this, and have never been able to find one.... There are plenty of pagination plugins for the post lists pages, but none (that I've found) for the single post and single pages... finally you have rectified this.
I would like to add some thoughts and criticisms about the plugin to help you with future development... do not take offense, as i mean it in a constructive manor.
First off i found your instructions just ever so slightly misleading as I (and i suspect many of the users of the plugin) am not 100% versed on the usage of php.
I found that the instruction to add the following line:
mysinglepages(wp_link_pages(array('before' => '', 'after' => '', 'next_or_number' => 'number','echo' => '0')));
to the appropriate places in our themes template was somewhat confusing...
The FULL instruction should read:
<?php mysinglepages(wp_link_pages(array('before' => '', 'after' => '', 'next_or_number' => 'number','echo' => '0'))); ?>
I know this will be very obvious to yourself and other theme developers, but it took me a few attempts to work out, and i would suggest that the majority of plugin users, rely on the use of plugins because they are very much amateur coders themselves... so a bit of clarity in your installation instructions would go a long way to helping us all.
The second problem i encountered was that once i had the code working, the buttons were not being styled.
I traced this issue to the code itself, using the plugin editor in my blogs admin area
It would seem that quite near the top of your plugins code, it is trying to call the css file from a directory called:
whereas, the ACTUAL name of the folder on the server is:
A quick edit of the code got the plugin working properly... I think this needs to be addressed quickly for your next release, as again, many users will not know this is the problem and will likely just dismiss the plugin as "broken" without trying to solve the issue themselves
(Just to be clear, i installed the plugin from the WordPress repository via my blogs admin panal - i did not name the directory, this is the folder name the plugin itself created)
With those two issues aside, i like the plugin, and it is quite close to being perfect... however...
One thing I DO NOT LIKE... is the fact that the navigation appears on EVERY post & page in my blog, even when it's not needed
I would suggest you try and find a way to ONLY DISPLAY the navigation on multi-page posts & pages...
at this time, that should be your priority... options for styling and number of pages to display in the navigation can all come at a later date
Unfortunately, until this issue is solved, i am not willing to use the plugin, as i think it just creates confusion to my readers if there is page navigation there when it is not a multipage post.
Again, i would like to repeat, that these minor complaints should be taken positively as i believe this plugin has a great future and i would like to see it developed up to the same sort of standard seen in the WP-Navi plugin that i use for my blog list pages
