avoidpartialspends and avoid_reuse from GUI
#341
Is your feature request related to a problem? Please describe.
avoidpartialspends and avoid_reuse are two important settings to avoid output linking, so I think being able to set them from the GUI would be a good improvement.
Describe the solution you’d like A GUI checkbox with a simple description on hover
The avoid_reuse flag can be set at wallet creation, but that dialog is already rather complicated. The flag can also be toggled for existing wallets. We don’t have a UI to change settings for the currently selected wallet, but we probably should.
Another approach could be to just have that as a checkbox in the send dialog. As an aside: it would be nice if the send dialog checked if it was about to reuse, and then showed a little warning text, something like: “This transaction reuses an address which may hurt your privacy. You can avoid this by clicking here, but it reduces your available balance.” This seems a better UX than hiding part of the balance, which is scary.
Adding GUI support for avoid_reuse is probably sufficient, because enabling that implies -avoidpartialspends:
0 -avoidpartialspends
1 Group outputs by address, selecting all or none, instead of selecting on
2 a per-output basis. Privacy is improved as an address is only
3 used once (unless someone sends to it after spending from it),
4 but may result in slightly higher fees as suboptimal coin
5 selection may result due to the added limitation (default: 0
6 (always enabled for wallets with "avoid_reuse" enabled))
