Cannot add TopLevelContents at the end of a Chunk

[eugenschindler]

How to reproduce:

• Create a toplevel item, such as a KernelF library
• Add an item in the contents nlist of the library, e.g. constant: val a = 1
• Now try to press Enter after this newly added item

What happens: you cannot add an item. Worst case, it may add a multiplication to a value or do other weird stuff.

Expected behavior: you should be able to add an item after the end.

Suggested solution direction: this quirk happens due to the projectional editor of MPS. It can be solved (or at least worked around) in the same way mbeddr did for its functions: by simply adding a read-only element at the end of a TopLevel content (like the "end function" in mbeddr), e.g.:

library A end library A <-- add this as a read-only constant, then adding new contents to the contents nlist of the TopLevelContents holder will be possible.

I don't understand what you mean. After you enter an item, you can press enter to insert one or multiple empty lines:

I observed similar behavior using Units:

A hotfix could be to provide an intention or allow CTRL+Enter at the end of UnitReference to create a new empty line.

I observed similar behavior using Units:

A hotfix could be to provide an intention or allow _CTRL+Enter_ at the end of `UnitReference` to create a new empty line.

The behavior for units is partilaly improved in PR #676. Can you check whether you can add a new line with the changes from the PR (by selecting the new grey bar as the EOL)?
