## Quick win: Explorer “Wallet” link

To add a Wallet link to the Blockscout/explorer navbar (e.g. on VMID 5000):

1. SSH to the explorer VM.
2. Edit the main HTML (e.g. `/var/www/html/index.html`).
3. Add in the nav: `<a href="/wallet">Wallet</a>`.

**See:** [REMAINING_TASKS.md](REMAINING_TASKS.md) § Quick Wins.

## Maintenance

- Update this index when new optional/recommendation docs are added or items are completed.
- **Updated:** Canonical list and derived views (ALL_RECOMMENDATIONS_AND_IMPROVEMENTS_LIST, HIGH_PRIORITY, OPERATOR_ONLY) are linked above and from [MASTER_INDEX.md](MASTER_INDEX.md). Do not use [ALL_IMPROVEMENTS_AND_GAPS_INDEX.md](ALL_IMPROVEMENTS_AND_GAPS_INDEX.md) as primary—it is deprecated (redirect only).
- Link from [00-meta/NEXT_STEPS_MASTER.md](00-meta/NEXT_STEPS_MASTER.md) if desired.
