[Feature request] Keysend message with amount

[Darth-Coin]

Recently https://amboss.space created a wonderful tool on their LN nodes explorer page: Keysend Billboard.

As you can see, some nodes can send a message using LN chat, but with a specific amount. I think they are using WatSat or something. In Thunderhub app, you can use the chat function to post messages on that billboard, but is default 1 sat, you can't setup a specific amount. Same if you try to use Keysend in TH, you can't put a meesage.

What about creating in Umbrel dashboard a small interface for WatSat or similar protocol to use keysend (amount) + message? Blixt wallet already implement it that. This tool is very usefull, nodes can announce their maintenance, merchants can post ads, it can be even like a LN-ebay, check this post :)
