I am still learning to use it but it seems this could be a useful tool after all.
The bottom part of the input box is confusing me all the time LOL

Thank you for your feedback!
Your input box confusion is noted, we've brainstormed some ideas on how we can improve the usability of this which will be implemented shortly!
Maybe adding short info when you hover over words, or add glossary with explanation.
Thank you for your feedback!
We love lightNING mode too
The definition of satoshi is at the top of the site, however we've just added a simple description of how to use the tool, above the inputs, in addition to the information icons thanks to your suggestion!
