Hello.
I've created a new ZDoom frontend called "ZDoom Executor".
Why create a new frontend if people seem to be content with ZDL?
Well, actually the idea came about after some ZDL stuff annoyed the hell out of me (mostly crashes when loading its own profiles and what I find to be some poor interface design decisions, along with the fact that development seems either dead or really stalled).
ZDoom Executor (zde for short

-What I believe is a saner, prettier interface.
-The program saves your options automatically on exit: no need to reconfigure your IWADs for every profile: they're always accessible after initial configuration from a convenient combo box.
-Exposes most of ZDoom's options (like controlling resolution from the command line, the idea was gathered from these very forums), as well as exposing everything ZDL does.
-It's fast to compile and fast to execute (It's written using Lazarus/Free Pascal).
-It should mostly compile and work for platforms other than Windows with minimal or no code changes (the code has been provisioned to account for several cases of Windows exclusive stuff).
-It's free! Both as in freedom and as in beer (GPL v.3 License).
-No need to have extra libraries cluttering your drive: it works out of the box and requires no external libraries (not even under Linux).
*Update 1.0.2*: Added the missing games (Chex Quest 1 and 3, Action Doom 2, Harmony and Hacx).
If you want to look at some screenshots; take it for a spin and maybe fall in love with it, or get your very own copy of the source code (SVN enabled, too) you can get it here:
https://sourceforge.net/projects/zdexe/
Only Windows binaries are available at the moment.
If you find any bugs, please don't hesitate to tell me, you can use this forum; if you have any suggestions, please do tell as well (though not every one will be used), also if some great artist from this community wants to contribute a better icon, it would be great.
Best regards
