It would be helpful if the custom spellcheck dictionary was searched for suggestions after the built-in dictionary was searched.
For example, let’s say the word
syslog was added to the custom dictionary by using the “right click on misspelled word -> Add to dictionary” flow. Normally, I would expect that when a word like
syslof is typed into the editor, that my custom dictionary entry,
syslog would appear in my list of suggestions. At the moment, my custom dictionary entry does not appear in the list.
