- LFT
I had hoped it used same rules as TNG for _PRIM tags, but you are correct, they only work for (***~LMO) modes.
(No idea what I was observing when I thought they were ignored in (***~ABS) modes!)
All the Notes appear to be present.
From the Media Gallery use the Edit option and all the Desc notes are in scrollable box.
Even if you simply double-click to open a Media Gallery image, its Desc box is scrollable using up/down cursor keys. - RMT
Seems to be like LFT and _PRIM tags only work for (***~LMO) modes. - FTM
Now uses _PHOTO in all modes including (***~LMO). Please test that they work satisfactorily.
Attached is Export Gedcom File Plugin ZIP Version 3.2.17 Dated 28 Jul 2017.
I believe this fixes all the _PRIM and _PHOTO tag issues you mentioned.
