Here is the official roadmap for the Link to Your Content plugin to give me something to live up to:
1.9 – May or may not get skipped in favor of 2.0. But if it is not skipped this is where the search update would be.
2.0 – The major update, complete tinyMCE 4.x compatibility, rewritten code, better panel functionality, updated techniques and technologies based on the myriad of things I have learned since first releasing this into the wild, and if 1.9 doesn’t happen search will be here as well.
Ongoing – Bug fixes as they arise of course, and translations are always welcome.
