LIYANAGE  I?m sorry about the 10.5 requirement, but I can?t change that because I use features that are only available in that OS release (Objective-C garbage collection).

These features made development and maintenance of the application so much easier that I decided to develop specifically for 10.5.  
(Version 2.0)

LIYANAGE  Assuming you refer to the size of the search result thumbnails, there are two ways to get bigger previews:

1.) the zoom slider

2.) hitting the space bar when a thumbnail is selected, that will open a QuickLook panel  
(Version 1.8)

LIYANAGE  MacFusion is *not* equivalent to ExpanDrive.

For example, with ExpanDrive I can put the laptop to sleep with all remote documents still open and take it home where it will connect to a different wireless network upon wake. ExpanDrive handles the network change gracefully, whereas MacFusion does not.

Switching back to an open document in BBEdit results in along hang while BBEdit asks the OS for the on-disk state of the document. Once it finally comes back and I try to save a changed version, I get the prompt "please insert the disk xxx". This means I have to close and re-open all documents, and this is simply unusable. The ability to reconnect transparently without remounting is essential.

I also don't think MacFusion does stuff like local SQLite caching or local handling of .DS_Store files instead of cluttering up the remote server. ExpanDrive is much more responsive, I see far less hangs when working with remote documents.

While it is true that MacFusion and ExpanDrive do the same basic thing, there is a difference in how well they do it.

MacFusion is a fine package, but ExpanDrive is a *much* more polished product, and of course it has to be for the price difference.

For the record, I am not affiliated with the company in any way, even if my comments about ExpanDrive here sound like a commercial :-) I just like the product.  
(Version 1.0.4)

LIYANAGE  This is simply fantastic. Tried it and bought it immediately. If you work a lot with files on remote servers via SFTP, you need this.

This is the first virtual SFTP file-system solution that works and doesn't hang the machine. I can even edit files directly off a remote volume with Office applications. This resulted in hangs and corrupted documents with stuff like sshfs.

I really like how the developers addressed the most important concerns from Mac users almost immediately in the last two updates.

Buy this. Really :-)
