Now what I am really missing is a Doom Launcher Frontend that is some kind of a library of all of your wads and projects to browse and play through. E.g. a launcher with a database where you can add wads/pk3s/whatever you have downloaded and where you can add screenshots, author, information, sourceport, maps etc. and also filter stuff like trhat. If possible, the mod could also show the titlepic of a project (if there is one) and all the other fancy information that the owner of this simply has to write/add to the database.
A very good example for functionality and interface is "D-Fend Reloaded" (a DOSBOX frontend, for those who have no idea what I am talking about). This would be a very nice way to sort, archive and play the stuff that you have downloaded from the community. It also needs the same functionality in terms of ports and IWADs that ZDL already has but that goes without saying I guess

Now, how hard is it to realize something like that? And is someone interested in doing something like that? I am sure it would be a very useful thing and as long as it is well-executed, I am sure that everyone would love to use something like that. It's comfortable and it's making mefeel sorted

Thanks for reading and let's hope someone is interested in coding this

Cheers,
Dan
