[BetterRed]

@bauerhjb - for two of my libraries I enter all the metadata into the book list cells, didn't notice any change in performance last week, just added 5 new items I had waiting to go into calibre 1.23 - no surprises.

My first two columns are author and title (which are set from file name) - after that its a mixture of custom & standard columns, including a couple of comments columns in one library. After entering a value I tab to next column, and repeat.

Just did a spot check cursoring around and hitting F2 and entering a value - seems normal to me.

Do you have any custom columns based on a program mode templates ? I ran into a performance problem caused by one of those once, nothing to do with versions though.

Oh, I'm not a high speed touch typist, bit better than one finger hunt & peck, but only just, so my expectations may not be as high as yours.

The library to which I just add the 5 items is ~7500books and 604GB (lots of audio, video, and transcripts etc). The other one is ~35,000 books and 30GB
