I’ve updated the Imieniny widget as follows:

• Added support for setting time offsets in the administrative interface.
• Added support for re-naming the widget title in the administrative interface.
• Cleaned up the code

Special thanks for the guidance from Kaf Oseo at guff szub. See WP plugin: My Widget – example WordPress widget.

The current version is alpha 0.3. The download is available from my Downloads page.
