Maybe this horse has been beaten to death already but how about JoinMarket?
I see Lopp use a script to upload the backup file to a cloud (dropbox in this case), maybe that’s a good App idea?
I’d like to see a way to add second password or 2FA for viewing private keys as well as withdrawing funds from the umbrel wallet.
I’d love to see a channel restore button in the GUI for Lightning.
You can already download your channels via GUI button, but there is no option to restore channels via GUI button. Sure, you can do it via command line, but not everyone has the capability to do those things. The goal of Umbrel is to make Bitcoin and Lightning easy enough for everyone to run. Therefore, I’d love to see this option built into the GUI.
Lightning Tab: 3 dot menu -> Restore channel backup
Prompt to upload previously downloaded file.
Execute lnd channel restore command.
Restore is not possible because the backup is not designed for that. The backup just closes all the channels for you and thus restore funds to your on-chain wallet.
Having said that, yes a proper backup and restore would be awesome, but it’s not easy.
I am confused. You can download a channel backup file now. And when you do an upgrade, you’re asked to download a backup just in case things go sideways. So, what’s this file then if it’s not a way to restore channels?
That file allows you to issue a command that requests all the channels to be closed down and thus the funds on your side of the channels will return to your on-chain wallet. The backup doesn’t allow you to restore your channels, only the funds within them. You will have to re-open new channels after using this backup file. Not ideal, but that’s the current state of things.
The reason you can’t backup the entire channel state is because the file would be huge and it changes very frequently. Basically every time a transaction is made, or any time somebody routes through your channels. Your backups would become obsolete really fast. You could build a system where the backup is uploaded to a cloud server every time any change is made, but it would be quite a bit of traffic.
Thank you. I understand now.
Please can you support password manager logins on the dashboard screen. Currently, Lastpass doesn’t seem to be able to fill in the password automatically, and sometimes it puts the username in the password field. It’s a small thing but it creates unnecessary friction when signing in.
2 Factor Authentication via Google Authenticator or similar
I’d like to also raise my hand for joinmarket support!
THIS!
ALREADY works on raspiblitz
Fee bump using RBF.
Lightning channel transactions have RBF flag but there is no way to bump the fee using RBF.
You can bump fees with RTL but it is a CPFP fee bump.
AFAIK there is no way to bump the fee by rebroadcasting RBF transaction with higher fee right now.
OMG this: https://github.com/accumulator/charge-lnd
It would save us all SO much time adjusting channel fees 
Great one!
I think it’s not up to the Umbrel team but the charge-lnd devs. They can submit the app to Umbrel Store.
Other feature suggestions:
Ground-Control Notification Server Integration
BlueWallet uses Ground Control, but you have to rely on their app / install for it to work. And I’m not sure if it will work when you use your own Electrum server.
We should have a Ground Control app for Umbrel or implement it into the BlueWallet app, so that we don’t have to rely on anyone else for notifications (which I believe compromise our privacy)
I’ll reach out to them / submit it, but I think anyone can and should run with it b/c they are clearly not running Umbrel and don’t care about it 
Another Feature Request:
Balance of Satoshis.
However, we would probably (almost definitely) need someone to build a GUI for this, as I think it’s way too technical and command-line for the average Umbrel user.
On that note, I just want to ask… is this really the best way for us to share feature requests? Perhaps something like Upvoty would be better, as it would allow us to vote on features, see in an organized fashion what’s been voted on, and then allow Umbrel team to show us what they’re working on?
Dark mode please!
I would like to remind of the extreme usefulness of having a decentralized P2P Exchange in the Umbrel.
The software on Bisq (.) network has it for Linux and someone could adapt or propose a partnership with this Exchange.
