The developers of this tweak, CocoaNuts, a few hours ago released a screenshot that shows some news about the next release of their tweak.
In the next release we will be able to enable or disable the incoming file transfers.
We will be also able to choose to import the incoming files in their native App or to save them in the default directory /var/mobile/Received.
Please note that ActionMenu isn't compatible with iOS 4.3.1 yet, so Celeste will not work on this firmware.
However, you can add this repo http ://iphone3gsystem.fr/cydia and install ActionMenu for Celeste for 4.3.1. This is only a temporary solution.
