Yes, that would be nice, but you might not ever see that one here since a package parser similar to the one that was written by Daniel15 on SMF would have to be installed by Bloc to work in the downloads section, similar to the package parser that is used on SMF in the Mod section on the right when you go to a Mod page. The last time I looked, Daniel15 had the source code for that available, but as far as I know it's still in beta and Daniel hasn't been particularly active recently with him concentrating on school. Several people run that package parser on their sites, but since it has to be updated every time a new version of SMF comes out, it is not always updated. When I want to check out the manual install instructions for a Mod I usually look at the PP on Sleepy's site here ---> http://sleepycode.com/PackageParser/index.php
but again, other sites have it installed as well. I've never looked at the code to see how difficult it is to keep it updated but from what I understand, it's not too difficult to do.
I just looked at it and it doesn't look like it's been updated yet for SMF 1.1.9
The reason I'm saying that it may not be something that Bloc wants to add is because this site concentrates on one Mod, that being TinyPortal. However, with all that being said, I agree that it would be nice to have that option available in our download section.
If you think this would be a good enhancement for us here on TinyPortal, you could place this into the BugTracker as a Site Feature Request and Bloc will have a look at it and toss it around in his head to see if he thinks it would be a good idea.
