5.0.1 update is coming soon, I'll try to upload it this month, it comes with a lot of changes:

The code is being improved to allow adding new features easily
Several variables, message keys, configuration keys are being modified
New .json files will be added for banks and player data

I'll try to move the data from bank.yml to the new player_data.json and the data from the bank section of config.yml to the new banks.json

I'll try to keep the keys from the configuration files in the bankinventory folder and make it compatible with the new version
