I remember liking trueSpace 4.x very much. There wasn't any big changes in the user interface. The new features were added into the button groups where they logically fit. More important, all the OLD buttons were where they were in 3.x!
trueSpace 5.x introduced a major update to the user interface, which included moving a lot of buttons around so nobody who'd used every previous version back to 2.0 could find anything. Fortunately in the configuration library it had tS3.x and tS4.x layouts that were almost, but not quite, exactly the same, but close enough.
So now here's tS 6.6 on my compy and no configurations that attempt to replicate any prior version.
I HATE THOSE #%%@#@#% 3D CONTROLS! I want to have the object and eye control buttons where they've been at the lower right since forever. WTH did they do with the point/edge/face edit buttons? Sure, any one can be found with the Icon Finder open, but I'd rather start with a ts4.x base config then add in all the new stuff where _I_ think it's a good fit. trueSpace newbies may get to feel right at home with 5.x and newer's layout but I just can not!
Aside from the layout changes, I wonder whose stupid idea it was to make the non-selected object wireframe color a slightly darker shade of white than the white of a selected object, then also use that same dark white for the non-selected object/group when navigating through a glued together object... How do I get them back to BLUE and ORANGE? The color selections in the display options don't appear to do a @#%%@ thing.
Bleah! trueSpace has always been a 'favorite' of articles on how NOT to design a user interface, but why did Caligari have to do worse and just change things apparently just to be changing things? Did they get 5,000 requests to make the default unselected object color dark white?
