Choosing where to store your data is a pretty basic feature of nearly all software
I strongly disagree on this. I can quote numerous online services that do not allow you to choose where to store your data :
- Any web calendar
- Any mail web server (who internally uses databases)
- Lots of online document editing services, like Google Docs, Etherpad, Zoho docs, and counting
- …
You should consider BW as an online service, not as an offline password manager with an option to chose where in your filesystem you want to store the database file.
One of BW’s major features is to provide an online sync and to be accessible nearly everywhere. In order to provide this, the service has been designed around a server providing an API that clients consume.
If you want to chose where to store your data, you have to host this web service yourself, and instructions are available. You can even ask for help here, we’d be glad to assist you in doing that
