Not sure if you noticed, but the SQLiteManager app and the SQLiteDoctor app have been updated recently by SQLabs.
For editing SQLite database manually, SQLiteManager is my favorite tool. Supports also CubeSQL database server and encrypted databases. And SQLiteDoctor has been very useful for us once to rebuild a broken SQLite database. We than exported with SQLiteManager the newer records created since the last backup.
Both are updated for 64-bit with a couple of bug fixes and enhancements, including HiDPI support for Windows.
