We have released ‘Load Them All’ v3.3 for QGIS

Changes in this version:

• Support JP2, KMZ, ERS, and SID files.
• Use addTabifiedDockWidget to show LoadThemAll panel on top of others.
• Add support for loading only geometryless layers (using GeometryFilter).

Additionally, this version includes a new contributor: Guillaume Lostis.
