Spellcheck:
Step 1: Make an entire project spell-checkable.
Step 2: Make sheet, view, and type names spell-checkable.
Step 3: Make schedule contents spell-checkable.
Step 4: Fix the bug where an infinite loop is entered:
Consider the text elements:
Drg.
Drg
Drg
Upon changing 'Drg' to 'Drg.' and clicking 'Change All', an infinite loop is entered. The text needs to be iterated through once, not whatever is happening.
You know it makes sense!
