The various ROM creators deactivated that button you need launchkey from the market and then you can assign that button what ever task you wish.
Glad you are enjoying the theme.
I guess I should have read the entire thread. Thanks. I'll try this now to fix rosie launcher. Weird but Rosie Launcher never installed. I flashed twice.
EDIT: Launchkey did work. I can now set the bottom right button to whatever I want. Thank you
EDIT: Just a suggestion but I would love to see a clear unlock screen.
EDIT: After installing Launchkey, it does work; however when exiting any application to that bottom right button, I get a white HTC screen then a screen refresh, which brings me back to the homescreen slowly. I'll try and post a video on it soon.
Here's the youtube link to my problem:

EDIT: Do not install Launchkey if you're Lightning Rom v3.3.1 / Adrynalyne 4.4.3. I also noticed that the application completely stopped working and rendered the launch button assigned dead, like it was before. FYI. Does anyone have a Rosie.apk I can flash to attempt to fix this?
