[phossler]

Trying to spell check a technical epub.

There are a LOT of words -- real and random conglomerations of letters e.g. FBI, IMPORTANT, UYTRE, NHYTGB, KJY1234, etc.)

I did try a RegEx like spell check filter ([!A-Z]* but it seems to filter out everything since the spell check filter only seems to match substrings

A checkbox option to not flag words in all caps or in all caps and digits would save a lot of scrolling with manual searching would be useful.

So 'words' like ABCD, OIJMNH, KJYNB12BB, QQQQ would not be considered misspelt if the option were checked. By product is that it would miss misspelt acronyms, such as FIB instead of FBI
