# History and Road Map

## Past

### 2015

- November: First implementation, simple data types, simple GUI

### 2016

- February: Implemented selection (the same item gets selected in all trees, changing a tab shows the same item)

- March: Implemented remaining local functionality (Copy Branch as Sibling, Copy Children to Siblings, Remove from this Tree, Delete Item)

- August: Created installable python package

### 2017

- May: Implemented new field type text

- June: Create deployable packages for Linux and Windows

- June: Made pre-release v0.0 available

- October: Implemented new field type node-path, re-wrote the way nodes move to new parents

- November: Uploaded package to pypi.python.org, TreeTime can now be installed using pip

### 2018

- October: Re-implemented the parent selection mechanism. The old cascaded menus have been replaced with single drop down lists.

- October: Re-furbished the GUI and removed a couple of bugs. Slighty changed the data file format. Implemented theme selection. Tested pyqtdeploy for deployment instead of pyinstaller. Updated the description.

- November: Released version 2018-10

### 2019

### 2020

- June: Fixed problem with protected cells (typing into a cell without data could cause a crash), and fixed file selection dialog (now only offers .trt files).

## Present

- Bugfixing

- Extend documentation on readthedocs.io

- Add more fields

- Add more examples and more template data files

- Structure editing/viewing in extra tab (editing the structure, number and definitions and trees and tree fields and data fields)

## Future

### Near Future

- Implement search function

### Mid Future

- Implement global functions (Linearise Tree, Level-Swap, Merge identical Siblings, Merge Identical Parents/Children)

### Far Future

- Implement safe usage by multiple simultaneous users

- Implement a database backend instead of text file storage

- A whole lot of other fancy things that will probably never get done
