Improve feature descriptions across the app

[TenSoja]

Description:
Some users have mentioned that certain feature descriptions (for example, clear cache for one tab) are not fully clear at first glance. This can lead to confusion and unnecessary apologies or questions from users.

Goal:
Make feature descriptions across the app more intuitive and beginner-friendly, so users immediately understand what each action does.

Impact:
This should reduce confusion, improve self-service, and make the app feel easier and friendlier to use.
