Considering that I've tweaked quite a few mods to my liking and it literally took me days to make the game run the way I want, after converting esps to esms and building new esps based on that, running patchers then installing some more mods, tweaking a bit and running even more patchers, changing textures, remodelling stuff, rewriting scripts, etc... ...no, I won't be doing all that work again just because the modmanager changed to a new system. And, if I lost my setup because of carelessly clicking "yes", I'd probably be sending death curses, too. On second thought... I could maybe put my whole data-folder into a zip file, call it my old setup and install it using the new modmanager. I might come back to this if I can't download mods with the 0.5x manager anymore.
