You know...we could really use an updated 2.0.X Net Launcher. Surely it wouldn't be that difficult...just change around the one or two settings that are now incompatible, like the color choices and whatnot.
Also, SSNTails, you might not care about the difference between console commands and total GUI control, but I do, and I think a lot of other people do. Yeah, I know that the Ultimate Launcher can do all these things, but (a) you have to remember all the desired parameter commands, and (b), it's a pain to type it all in manually.
Another thing: one of the reasons I liked the Netlauncher a lot was that it allowed you to browse for WAD files. If that feature isn't there, what's the point of it? You could just use a bunch of batch files which are configured to every combination of settings you like to use. Hell, you could probably make do with just a single batch file that loads your favorite settings. But WAD files are another matter; many people are always changing the combination of WADs they add in, and the option to browse for the files in a GUI is an invaluable tool.
