Concept - Carbon Fiber Series 1.0.2

"To reach the advanced settings go to puff info then choose reset and you will be able to reset the device statistics on the next screen as well as choose advanced options" 

Yeah - that sounds really intuitive. Puff info > Reset > Advanced options. Where else? 

Nowhere else . It seemed to be the optimal location to place the option. The advanced screen was placed there to offer those settings without intimidating new users. Some people like to reset the stats every day while some like to do so to give a rough estimate as to coil change on sub-ohm tanks. Myself I don’t bother with resetting however I do use stealth mode.

Yes, okay. But shouldn't "intuitive" user guidance mean that functions are located where the user expects them? Or guide him there in a targeted manner?
With the best will in the world, I cannot imagine that a - just a new - user would come up with the idea of looking for the power bank function after "Puff Info" and then via "Reset". He will find the function somewhere after "System "or in connection with the batteries. At this position you actually hide the "Advanced Options" - my opinion.

Your division offers a very suitable place: Set the item "Advanced" instead of "About" on your system screen. From the Advanced Screen you can then link the About Screen; whereby this is actually completely overrated ...

For example, the "Settings => System => Brightness" path (which you also implemented) is intuitive. An advanced option for brightness is the stealth mode. Nobody would think of looking for it on the path "System => Puff-Info => Reset => Advanced => Stealth".
A user who is not interested in the chart display will not reset it either - the advanced settings will remain hidden forever.

BUT - apart from that, I think your two current themes are very successful in that new users in particular are not overwhelmed by the possibilities of the chipset and switching from the default theme is easy. All functions are also easy to read - which is not the case here with many themes. Basically, I like your current development.
