Issue with 0 XLM Accounts

[Smephite]

So I may have a oddly specific problem:
I like to use 0 Lumen accounts for esthetics.
The problem with those is that I need another account as sponsor to do any kind of txes, such as claiming balances.
I'd love to have the possibility to make use of an other account sponsoring the tx / doing a fee bump or at least the ability of outputting the signed XDR to do a fee bump manually.
Also if your account is underfunded it will just fail and not do anything UI wise (no error).

Thank you for the report!
I was already thinking of adding a TX output. Specifically SEP-0007 QR Codes.

In general all multisig-scenarios as well as channeled transactions are not supported, yet but I want to add them.
