The important thing to note is that any customisations you’re made using Ribbon Workbench will still work- you can run your ‘classic’ customisations alongside modern ones you’ve created with the command designer no problem- in fact, the death of Ribbon Workbench may have been prematurely announced… while the command bar is a HUGE step forward, it’s not as fully featured as Ribbon Workbench yet, so if you’ve got complex requirements, you’ll likely have to switch between the two tools – note though that you won’t be able to edit your ‘classic’ commands in the ‘modern’ command designer.
A couple of things we’re waiting for with the command designer:
- Full bore PowerFX support – some functions aren’t supported at the moment, and the intellisense might suggest something that isn’t supported, so watch out!
- Component libraries currently need to be shared with users who want to run or customize these commands – you won’t see them just because you’re a system administrator!
- We also can’t share these between different apps (so you’ll need to re-create a command to share it across apps or locations).
- Custom visibility rules aren’t supported.
- Dynamically populated buttons aren’t supported.
