GD Custom Posts and Taxonomies Tools Pro 3.0 is soon getting into active development cycle and I am still working on the list of features to include in the major plugin revision. Here is some preliminary info on what to expect in the new plugin version and when to expect it.
Before 3.0, there will be at least 2 minor revisions of current plugin version to improve on existing features and fix some bugs. Next 2.6.6 version will be released over the weekend with few bugs fixed and other minor changes.
As for 3.0, user interface will be improved to provide more on screen information. It will use similar method I have made for upcoming GD Star Rating 2.0 plugin using tool tips. There are many options available for custom posts and custom taxonomies and it can be overwhelming for users to understand what is used for what. One of the most requested feature is support for simple meta boxes for default and custom posts types that will allow setting number of custom options to use with shortcodes and functions for inserting into the post. Tools for importing and exporting settings for custom post types and custom taxonomies will be included, so you can easily export created elements to import on another website.
These are preliminary features for new version, but all suggestions are welcome. So, if you have some interesting idea for this plugin, please leave a comment for further discussion.
