The user interface is what the user has to do to use the program. This is not supported in Wine. You will find links from winehq to several lists of things that run under Wine. When you attempt to use these lists you will find that many if not most of the programs do not run as is. The user outside the Wine world sees a totally false picture of Wine. He loads Wine and finds there are NO current instructions on how to use it so he presumes Wine to be worthless and goes away. Even if he persists there is still the problem of figuring out exactly how to make many if not most of the programs in the will run database work. The public simply won't put up with this. You can't have Wine so that a user must be a priest to load a special dll or to find out what special dll is necessary. Currently, there needs to be a short document written and KEPT up to date. To install and use Wine do ....... This document needs to point to somewhere where the user can get more help. There needs to be a WIKI where postings can be made specifically concerning what is necessary to make a program work on Wine. How do you currently make Office or Acrobat work on Wine? To my knowledge there are currently no large or complicated programs that you just load and run under Wine. You must set them all up first. It doesn't make any difference to the user if a program fails because of a sound driver. Waiting for all this to be fixed perfectly means a wait forever and serves no purpose without at least simple instructions on how to use Wine now.
