This conversation has been merged. Please reference the main conversation: Camera Raw 12.3: How to revert UI to older version, one with vertical filmstrip?
If any programmer that makes changes to software, making it more of a struggle to work with, with more unnecessary clicks, thinking he/she provides users with an upgrade, please get them back to school! Adobe, we did not ask for this 'improvement'. Because it is not, it is a setback. This has nothing to do with 'getting used to it'. It is just really crap UI.
Please get the older UI back, so much better as it makes my workflow more efficient. That is all that counts. Listen to your customers and do not come up with changes without -at least- test it with professional customers (!) A dissatified customer.
