Thanks,

I will check it out on Monday.  Could be very useful.

>        selectedLayers = iface.layerTreeView().selectedLayersRecursive()
>         for layer in selectedLayers:
>             layer.startEditing()
> ;Do your stuff here
>             layer.triggerRepaint()

> I've created a basic plugin (https://github.com/djes/MultipleLayersTools) for my own needs, take a look at the code. If I have time I could add some of your needs.
> Btw, using geopackage is great for exchange and backup. But a real db server is a must have.

>> Before I go to my default mode and python my way through this, is there a plugin that would permit me to perform batch operation on all the layers found in a single .gpkg file?  My geopackages contain hundreds of layers (from autocad) (contain identical data structures) and I would like to do things like:
>> 
>> Perform field calculator operations on each layer within the geopackage
>> Split all geopackage layer with a field
>> Merge multiple layers in a new geopackage
>> I guess FME would be another way out? I there an OpenSource equivilant to this? (I have a home version but I need to respect the license for this one.)
