Legacy Titler has a bug
With the old legacy titling editor you have to manual enable the tools and properties panels. The old titling system gives you a lot more options and it is much easier to use. Adobe needs to continue supporting it. I have a video of the bug.
THIS. I came here to say this. It's is INFURIATING. I have to manually enable the properties, actions and tools tabs EVERY TIME I want to manipulate a title. It's bonkers! ADOBE, fix.
