Can clippings be sorted by resource and or the page in the resource they appear on?
Sorry, you can only rearrange clippings by dragging them. However, see this post for a possible workaround: https://community.logos.com/forums/t/127918.aspx

Very helpful.
Do you know of a way to assign a tag to more than one clipping at the same time?
Also I've noticed that sometimes a tag is automatically added. Do you know where that comes from?
That is not possible.
Automatic tagging comes from the source of your clipping; whether a headword or scripture reference.
