If you found this useful, it would bring me great joy to see your work - so be sure to share. :)

Or, better yet, please feel free to dump a bitcoin or two here:

... include a note to the effect of "Hi Julius3E8, thanks for the Everlasting Gobstopper thing... my life has improved five-fold on account of it and please accept this paltry amount in gratitude".

You're welcome! (in advance) :D

Also, feel free to peruse my other submissions which are almost as varied as they are many:
