This topic spurred a thought in my brain for an enhancement to the Spell Check Tool:

Long story short, it would be a nice feature enhancement to have a checkbox to allow a Case Sensitive SEARCH.
For example, searching for a capital letter 'O' will allow "Octopus" to be shown in the list, but not "octopus". Searching for a capital 'I' will show "McIver", but not "Mciver".
Having the checkbox off will be the default (current) implementation (not case sensitive).
As I mentioned in that topic, I believe a Case Sensitive Search would be extremely helpful for catching many of these hard to find OCR errors (capital 'I' instead of lowercase 'l', etc. etc....)
