Absolutely, in fact despite knowing that it'll be utter crap, the rev pack motivated me to make a video because it looks just so much better. Shows that LFS can look decent even without touching the graphics engine
The installer includes all files that were made until now (also with the latest bug fixes).
About the menu backgrounds, if you download the files from the original link (without installer) you will read: "Unfinished Addon", and will also notice it doesn't include these menu backgrounds you mentioned. http://www.megaupload.com/?d=G2JQWK2X
So, the installer is complete with all files available until now. And I'll create patches for it and update the installers if Lynce make any other updates too.
