This has been available in C4D for quite some time. They just changed the default functionality. Can be changed by right-clicking a field and choosing a User Interface option.
I'll just reiterate what some other folks have said... the UI was the last thing that needed attention in this update. They've got time to update the general UI, but leave the xpresso UI untouched...
I reached out about upgrading my perpetual R21 license to R25 perpetual. How can I justify paying $2100 for that? I've compiled a list of features I'd be getting:
Slight UV improvements
Organized viewport filters (geo only mode)
Character pose library
Magic Bullet Looks
Content/Asset Browser updates
Object placement tool
UI update
I know I've left out some other tools like gltf exporting, delta mush, timeline filtering, deformer indicators, scene nodes (not production ready), python 3, tween tool, etc. But honestly, none of these are absolute game-changers that can justify paying $2100 for.
I guess gone are the days of big releases like R20 when we got fields, CAD import, volume builder, node-based materials, updated gradient, etc. Just packed full of useful workflow integrations.
