I’d like to think that since its inception WP-Slimbox2 has come a long way and that there’s not really much further to go. Having said that, I can think of a few changes that can still improve the plugins functionality over all.
One of the first things I’m looking to do is to utilize the copy of Farbtastic that’s already included with WordPress. At the time I implemented it WordPress did not include Farbtastic (I’m not sure it included any sort of color selection), and after searching I decided that Farbtastic was the best choice. Turns out the WordPress team thought so too, since they went ahead and incorporated it into a later build. Now that it’s included, I can remove my own copy and update my code to utilize it instead. Ultimately this shouldn’t really have a direct impact on anyone, but it does make the code better.
Another thing I’m looking at is to more extensively utilize the Settings API. Apparently it can be used for the entirety of your settings pages, so I’m going to see what I can do. At most, this should only affect the appearance of the settings page, but it also should improve the code.
Another feature that’s been requested at least enough time for me to consider it would be the ability to replace the bottom “info bar” section, where you can display the URL and/or caption, with some sort of customizable code. Be it for social media purposes, or a special downloading script, etc. Again, I can’t say this is possible such that it could easily be utilized by everyone, but I’m definitely going to see what I can do.
