1) Can you please put the default phone number back on the favorites screen or make it an option. I like seeing what number will be dialed before it dials. It would be useful to have the same behavior on contact search screen where clicking the name dials the default number.
I understand what you are saying re
reformance and I'd like to say I will use it, but if I can't see the number I know I won't use the feature. I just don't remember what the default # might be and I always want to know what number is being dialed before I dial it. FWIW, I never saw a performance issue on this screen but I did not test this with a large favorites list.
2) The is an issue on the contact search screen when you delete all the search letters. The search letter text overlay doesn't disappear even when moving from screen to screen. I had to change apps to get it to disappear.
The overlay looks like it never disappears even if you don't hit backspace. Also the FC when you dial from the contact search result is back. I'd request reverting to the 1.6.8 version if you can. That version was working fine. This new version is definitely janky compared to 1.6.8 and with that overlay not disappearing and the FC it makes the contact search feature unusable.
3) This is a nitpick but you seem to switch between American English and British English eg "Header Color" vs "Text colour for contact list".
There are a couple of other typos in the settings pages you might want to look at.
4) Changing fonts caused a FC
I submitted a report. I can't reproduce so maybe it only happens on the very first time you set a font.
