Okay, I have a possible bug as well as a suggestion for an update.
Since installing this module, anytime I type a caption and want to go back whether to correct a typo or add something, instead of just placing the cursor where I press like normal, it automatically selects the nearest word and brings up the replace button, which is really annoying and prevents me from going back and doing what I want and should be able to do. Is this a bug and can it be fixed in an update? Also, as pointed out, the red lines for typos bugs me as well.
And the suggestion. Could it be done so that as well as unlimited caption typing, multiple caption boxes can be used? For example, taking a picture of a face, and selecting empty space above the face and typing out whatever, then selecting empty space below the face and starting a new caption box? I suggest this merely because if you try to space it out as such, you won't be able to close out of the caption box and send the Snap, mainly due to the bug (?) above.
