Things like the mirrors in the 60's cars, steering lock that doesn't auto-adjust on Fanatec wheels, various other UI issues like the dual map display when selecting a track, etc., so that when each update is released it can confirm whether or not those issues are supposed to be resolved. I understand that there is an order to fixing things and that even though it seems strange that well known, glaring bugs are still present in subsequent updates, it is annoying to not know what is supposed to be fixed and what is not.
I would add that an estimated graphics performance change would also be helpful...again so we can calibrate whether we are experiencing something resembling what is expected. For example, I got a nice performance improvement with 85 and then none with 101. I hope there wasn't supposed to be one with 101, but....how would one know one way or the other???
I'd appreciate feedback from others. If we agree, I am sure it wouldn't take much for ISI to post a sticky and we could even nominate the "major issues" that we would like tracked.
