The Add-on installs all of the released formulas made by Top Contributors, like - MATRIX, SQLJOINS, CONSTANTS - ROWTOTALS, UTILITIES, BRAILLE, MORSE - JAVASCRIP, JS_MAP, JS_SORT, LEVENSHTEIN DISTANCE Except for the UTILITIES, the formulas themselves use only JavaScript to perform their magic in presenting the result and no service is evoked during operation which (in many cases) leads to a shorter processing time.
