When I have finished a research level I get a nice note about it..
But seemingly this note is of little use, as it does not specify what goods/shops/facilities I actually just have developed.
Perhaps the 'automail' could specify what exactly I acheived by finishing 'this new level' - because after the research of the level is done, I have no way to tell what I gained, except by looking through all of the build-options, and try to remember what I had before/after the research.. 
Whenever you research it tells you what you are going to be able to manufacture. the 3rd line down and the 4th line down shows you either what is new to build or what is new to make. 
EDIT: then you can just note what you are able to build or make.
(or you could check the research database)
a overview of all researches depending the level would be nice
e.g.
Level 0 : .........Rubber, Wintercloth....
Level 1 : ..........
or a list where u choose the level u r and depending on it all goods u can produce r shown
yes,
can we get some reply from developers? 
Such a list exists, but it was disabled while changing the server and design of our portal.
stdok manages the portal, i think he will implement this view in our new portal shortly *to give a broad hint @ stdok*
