Hi there!
I've made a tool visualizing transactions flow: https://ratingers.pythonanywhere.com/tx-explorer/

Features:
1. Tracking multiple accounts. Just enter contract address into text field and possibly a name next to it.
2. Showing account balances.
3. Decoding known opcodes (currently jetton-related; NFT ones are not yet added).
4. Showing transactions in order as they happened, including external messages and messages from/to untracked accounts.

Known TODOs:
1. Add more opcodes to database.
2. Create button to easily add untracked peer of a message to track.
3. Loading transaction exit codes and fees.
