[UX Improvement] Opening channel details

[Darth-Coin]

NOTE: _@fiatjaf this is just a proposal, no rush or bug, is just an observation to improve the noob experience with OBW.
So please before closing it, think about.
EDIT: Maybe is a bug, in the end. after 12h waiting for mempool to clear up, the tx is not confirmed but the channel is still in pending.
The peer confirmed also that have the channel in pending but no tx confirmed. Weird.

Description

Add more details in the opening channel procedure.

Actual behavior

The onchain balance remain the same after the channel opening is initiated and also the sats for the new channel are reflected into LN balance (and is not right).

Expected behavior

The sats from onchain should be gone, or at least in the brackets or other color, to indicate that are in pending or something.
Or make the onchain balance 0 (was sent all sats available) but add in LN balance, in the brackets the opening channel amount, next to the real LN balance.
I don't know how you can fit into that small space, but at least inform the user that those funds are STILL NOT available.

Notes

• I funded the opening channel with a quite low fee under the mempool recommended (testing), 5sat/vB, when low priority was 25 sat. That could explain why the tx it doesn't appear yet in mempool and/or in OBW tx log
• So I kept OBW open for a while
• I don't know whata new user of OBW should do in such a case. There's no other instruction in the app.

This is what I get when I click on pending channel:

As old tester for wallets, I understand what is going on, but a newbie that will install first time OBW will not know that will have to wait and will do crazy things and/or complain where his sats...

OK, we've tried again and seems that is working.

Now the funds are taken from onchain and appeared the tx in logs.

But the displayed balance in LN is still wrong.
Maybe was just due to mempool too busy and the tx was rejected by miners being too low.

Now channel is opening normally, will try to close the previous one, to see what happen.
Like in this amazing theory of everything: for more you fuck around, more you find out :)

So fucking around more, to find out more, I click on force close the pending channel, just to see what happen.
Will wait to see when will be eliminated from there, having nothing to close.

After I initiated the FC for the old pending channel, the pending sats disappeared from LN balance (is correct) but I have this sign on top right, I don't know what represent. Also the FC tx appear like pending, with those 300k sats that are from nowhere.

This is nice warning for the user
