Idk where you are taking bugs, if at all, but one thing I noticed so far:

When you create a custom command with the action "Open website", the URL is always converted to lowercase. This shouldn't be so because some URLs are case-sensitive.
For my scenario, I tried to set up a "!discord" command but the "discord.gg/5EtScrf" becomes "discord.gg/5etscrf" which is an invalid link.

Thanks for your work on the mod though!
