If protocol handlers in the operating system and/or in a web browser are broken, it is not possible to download new filters from the web site.
The obsoleted in-program library browser (which I'm guessing may not be in newer versions of Filter Forge) is (at least in my case) terribly slow, and searches from it for filters which I know exist at the web site fail.
Consequently, users in some scenarios can be totally unable to acquire new filters for a program that was sold with a promise of an ever-expanding library, and/or the ability to download any of many thousands of pre-existing filters, as a sale point.
There are probably more users in that situation than you might think. There are many forum posts about this problem, many of them not resolved.
Also, users should not have to buy the available extra purchase library tool. That tool should come with every filter forge license (and made retroactively so), or even better, it would be great if it were free.
I think there should be direct filter download URLs made available to users via the web site. The lack of them, in some settings (and probably more often than you might think) breaks a core selling point of the software.
You refer to the prophecy of the pastry that will bring balance to the Force. And you believe it's this...donut?
