They keep compatibility but abandon a lot of stuff. If they switch to JavaScript VBA development will slow to almost nothing and it will take years for the JavaScript stuff to catch up, if ever.
Something similar happened with visual studio. 2008 was really nice, very customizable and fast. Then they redid everything in 2010 and the result was slower with way less capability. And even now there are still a lot of features that 2008 had not implemented.
I also love vs2008 over vs2010 and still use it for some projects just because it feels so nice and snappy.
But which features exactly are missing in vs2010 that were in vs2008 (except the snappy feeling)? I have not actually noticed anything missing and would like to know more
2008 had an excellent macro recorder which was gone on 2010. 2008 had an easy way to customize toolbars and menus by drag and drop. With 2010 setting up a toolbar is much harder. There were a few other things but I don’t remember right now.
