# Version 6 Road Map # {#v6_road_map}

This document is the KiCad version 6 Developer's road map document.  It is
living document that should be maintained during the version 6 development
cycle.  The goal of this document is to provide an overview for developers
of the goals for the project for the version 6 release of KiCad.  It is
broken into sections for each major component of the KiCad source code and
documentation.  It defines tasks that developers an use to contribute to the
project and provides updated status information.  Tasks should define clear
objectives and avoid vague generalizations so that a new developer can complete
the task.  It is not a place for developers to add their own personal wish.
list.  It should only be updated with approval of the project manager after
discussion with the lead developers.

Each entry in the road map is made up of four sections.  The goal should
be a brief description of the what the road map entry will accomplish.  The
task section should be a list of deliverable items that are specific enough
hat they can be documented as completed.  The dependencies sections is a list
of requirements that must be completed before work can begin on any of the
tasks.  The status section should include a list of completed tasks or marked
as complete as when the goal is met.

# General # {#v6_general}
This section defines the tasks that affect all or most of KiCad or do not
fit under as specific part of the code such as the board editor or the
schematic editor.

## User Interface Modernization ## {#v6_wxaui}
**Goal:**

Give KiCad a more modern user interface with dockable tool bars and windows.
Create perspectives to allow users to arrange dockable windows as they prefer.

**Task:**
- Take advantage of the advanced UI features in wxAui such as detaching and
  hiding.
- Study ergonomics of various commercial/proprietary PCB applications (when
  in doubt about any particular UI solution, check how it has been done in a
  certain proprietary app that is very popular among OSHW folks and do exactly
  opposite).
- Clean up menu structure. Menus must allow access to all features of the
  program in a clear and logical way. Currently some functions of Pcbnew are
  accessible only through tool bars
- Redesign dialogs, make sure they are following same style rules.
