There is an old principle, keep it simple; especially if something is going to viewed rapidly.
So, if I may:
* Old HM2 hand viewer and new HM2 hand viewer are not simple. I find them confusing because of the duplication of data and inclusion of data that (to me) is not essential. The viewer needs to be scanned quickly, that demands lean and mean.
* I also think the grey theme is not conducive to rapid scan. For me, data gets lost in the background.
* The mix of small and big cards, or just big cards, just adds to the confusion and makes my eyes bleed.
To meet my needs, HM1 & PT4 hand viewers work a treat.
Naturally, all the above is personal opinion only.
