I simply use VL's (Virtual Libraries) for this. No custom columns (for that) needed.
No Formats (VL)
Code:
(formats:false and not #master:LNK)
#master is where I log the original start. LNK is what I log when I used EPUBSPLIT to make that
I have VL's for: Have Read and To Read (/ Reading) (the filter is #done (a date)
