I would like to request the addition of custom dictionaries to the spellchecker. This is different from adding words to the user dictionary.
Certain fields, like biology, have massive dictionaries with the number of unique words approaching several tens of thousands. These fields are also (understandably) very pedantic about words and their spellings. I think it would be useful to have an option in the spellchecker options to add pre-made dictionaries to the spelling list. There are many “.dic” files available online for integrating these dictionaries into Office and other word processors. Obsidian can use these files in its spell-checker too, allowing it to tap into existing dictionaries without the mess of converting files into different formats.
For reference, here is an example of a dictionary with a long list of words.
I have already tried to copy the words I use in my Office dictionary into
.obsidian\config under the “spellcheckDictionary” variable, taking care to format it like a JSON file. Obsidian didn’t seem to like that as it reset the config file immediately when I reopened it. This doesn’t seem to be a good option.
