Hello, I like STSdb, so I made a small tool called STSdb Explorer, based on the Sample.Advanced project.
What it does:
1. support view/modify/delete/compact record and database
2. support lambda expression query
3. support any database against any application/library even though the key/records are custom types.
Anyone who is interested in it, can download the source code from:
