Whenever you are watching videos, whether in window mode or full screen mode, clicking the left or right arrow keys on your keyboard will flip forward and back through your active playlist.
YaYa v.9 is now available here and at the Adobe Showcase. This version is a must have if you like the app because it adds a lot of new things and fixes a few others.
Some of the features of the v.9 release:
1. Totally reworked multiple download routine. The list of returns is now repeater based instead of itemRenderer based so when you scroll while downloading, every active download is tracked as it should be and progresses as it should. Refactoring was causing major problems using a renderer and if you scrolled the list while downloading an item things went wonky. Not anymore.
2. Exit awareness during downloads. If you attempt to exit with downloads in progress the app finishes all downloads and library queries before exiting and notifies the end user of such.
3. Library playlist queuing. Now you queue items from the library to the video player. This is more natural. This way you can use the filters to narrow down what you are looking for…select from the narrowed down list and queue them up.
4. Added YouTube username search. You can now search by keyword or YouTube user.
5. Added a new “Hide Controls” mode. Click the box and the entire application window becomes the video space.
6. Display of Publish date (by user request).
7. Search progress indicator. Just a visual so you know the app is searching YouTube.
8. Version check from app. If your version is current you are notified. If not you can download new version.
8. Many background tweaks not worth mentioning.
Nirmal T V from Life Rocks 2.0 was kind enough to write about YaYa at his website recently and it’s apparent he actually tried the app from his screenshots as opposed to simply cutting and pasting some text for the sake of it. Coming from a guy as talented as he is, it put a smile on my face to read it and for that I thank him sincerely 
I released "YaYa" (Yet Another YouTube App) 1/25/10 to the Adobe Showcase.
YaYa lets you search for YouTube videos and download them to be added to a local library. Your library supports favorites and title searching to create customized playlists selected from your favorites. YaYa can simultaneously download videos to be directly added to your library. YaYa supports drag and drop of FLV’s right to your library too. You can take screenshots of your videos as they play and export them as JPG or PNG files right to your YaYa folder in your documents directory. You do not need an internet connection to view your local library but of course it’s needed to search YouTube and add videos to your library.
This app expands on in-R-tube in some very significant ways. Mainly the library is now database driven (SQLite) so it allows me to do things like allow library searching and bookmarking. You can bookmark videos in your library and then only show your bookmarks to create a custom playlist. You can title search your library to create a playlist as well. The screenshot ability has also been improved upon and you can preview all screenshots and remove any unwanted screenshots before exporting them. You can export screenshots as JPG or PNG. Another upgrade is the multiple OS support. in-R-tube was Windows only but YaYa is for Windows, Linux or MacOS thanks to Adobe AIR. Instead of single video downloads, you can now download multiple videos at once to be inserted directly to your library.
Tonight I’m adding to it a bit. I’m adding the ability to shuffle the playlist, adding support for “genre’s” and tweaking the library search to allow searching by multiple criteria if desired (like search for all bookmarked videos with genre of rap). When that is added the version will be updated from v.3 to v.4
