Hi,
I'm testing v5.3.0 on the iPad Air 2 with iOS 9.3.3 Public Beta 1 installed.
The new design is better then the old one. Changing the color of the field names with the color of the icon is nice, but for me it's not important if the field names are written in black or in another color. But the apple icon is a light gray and also the field names of the Apple entries are light gray, which is very hard to read.
Expanding the password length is always good. Can I ask why to 50? Is a unsual length in IT.
The new "exclusion symbols" feature is a good improvement, but I know some webpages, which only allows dots and dashs for their passwords. Maybe it would be nice to include an option to say only this symbols, because I don't want to write all symbols except the two allowed ones.
