Hello,
If you have a specific request for improvements/ additions let me know.
We are currently working on the ability to upload/ download large files using Active Site, a progress bar will indicate the upload progress.
The files will be stored in an encrypted zip file - there will also be a seamless download tool to download/ decrypt/ unzip the zip file.
FYI - this add on will be accomplished using Java applets.
All the best,
Ian.
