I love everything about the new update (especially the much-needed visual makeover), but I have one small complaint. I'd like the old input "autocompleting text field with dropdown option" for the singleplayer PWADs box to be ported back: the new dropdown button doesn't work well and is slower.

Can't do this anymore. Enter doesn't work to add, up/down keys don't look where the last selection left off, and autocomplete likes to randomly think every letter is the first letter to look for. Needing a lot of clicking, it feels clunky now. Everything else relies on tedious manual open file file dialogs, .cfgs, what have you, so IDE's always been a great exception.
Just the two cents I hope to be considered in a future update, IDE's the only launcher that was so fast and easy like this and kept a "database" of wads to quickly sort through and use.
On an offtopic note, thanks for fixing support for files with spaces in the path.
EDIT: Oh, and the Add button doesn't turn into a Replace button on loading a config. Can't edit my configs now. Oops.
