# 1. Basic UI and navigation

> Understanding Pensiv's overall structure and navigation

Pensiv is not just a document tool.\
It’s a **thinking system** where files, relationships, structure, and tasks connect in one space.

This section explains how that structure is organized\
before you learn individual features.

***

* [1.1 Pensiv’s overall structure](/en/guide/basic-ui-and-navigation/structure)
* [1.2 Main navigation](/en/guide/basic-ui-and-navigation/main-navigation)
* [1.3 What is a section?](/en/guide/basic-ui-and-navigation/section)
* [1.4 Understanding panels](/en/guide/basic-ui-and-navigation/panel-split-view)
* [1.5 Pensiv UI terms](/en/guide/basic-ui-and-navigation/ui-terms)

***

Pensiv is

* not storage-centric,
* but role-centric
* and connection-centric.

The UI can look busy.\
The structure is consistent.

> Navigation → Section → File → Connection → Structure

Once you see that flow,\
Pensiv feels lighter and clearer.
