Suggestion: give begin and end barlines their own subtype
The point here is to allow for Select Similar filtration so that a user can easily span all end barlines but not, for example, the in-between, or similar activities. I haven't checked the code, but theoretically, this shouldn't be that difficult I'd imagine. I wonder if others would find this desirable?
For an example of what was mentioned:
It's one thing to manually do this for one system. To do it for an entire score takes some effort, let alone potentially complicated multi-instrument scores with different situations, but it would be merely two or three operations with begin/end subtypes for barlines with filtration.
