Configurable number of Ledger wallets

[gw0]

Currently, when using a Ledger device with the Oasis Web Wallet the screen "Select the wallets to open" only shows the first 5 wallets to open (by derivation path).

Power users will likely want to use more than 5 wallets per Ledger device. Possible solutions:

• Configurable number of Ledger wallets (hidden under an "Advanced" tab or menu)
• Option to manually specify derivation paths to import.
• Iterative retrieving of Ledger wallets until it finds e.g. 2 empty/never-used wallets.

The library seems to support a count parameter that is set by default to 5:

We probably want pagination or specifying paths, because listing accounts from ledger is so slow:

• ledger s: 5 accounts: 6429 ms
• ledger x: 5 accounts: 2560 ms
