Add an option for persistent spell checking
As a technical writer at Red Hat, I'm trying to use Builder to write our documentation. I'm really enjoying some features of Builder, like the fuzzy global file search, which fits our repo structure very nicely.
However, one thing that's critically missing for documentation is an option to persistently highlight spelling errors. Currently, I can open a spell checking sidebar but that requires an explicit user action (which I'll likely forget to do) and I can't see errors as I type.
Ideally, I'd like Builder to expose an option in the Programming Languages configuration so that I can enable automatic spell checking in all AsciiDoc files. Errors should be underlined or highlighted in a similar way.
For reference, GEdit already has the Highlight Misspelled Words option, although you have to manually enable it for each file.
