Make Tipps&Tricks more prominent and try to keep it up-to-date

[murggel]

The list of hidden features is kind of "hidden" in the manual (under section Special functions and hints at the end)

It should be enhanced with the latest long-taps

It can be also renamed to "Did you already know this?" or something like that. The naming "special functions" probably leads to ignoring it for basic / unsecure users.

Alternative / additional

Having a "wizard" / overview in the app itself

Idea from c:geo-booth at Event Tanz auf den Vulkanen
