GTG's integration with GNOME Shell

by Baptiste Saleil

GTG is simply the better soft to manage personnal tasks with all features a user needs. Also, I use the so friendly Gnome-Shell since the begining of his young age. So, my idea is to work on GTG software, to create the better link as possible between GTG in one side and Gnome-Shell in the other one, to improve usage and rapidity. By this way, the user could manage his tasks (Create, edit,...) directly from the shell with a friendly and unified interface.

Extension for GNOME Shell


This extension is available on GNOME Shell extensions website with the name "GTG Integration". To install it, you can simply go to the website, search for the extension, change the switch button to "ON", and accept download. It is now installed. This extension bring many features described in next section.


Search in overview
This feature is simple to use. Open the overview by pressing "super" key or move your mouse on top left corner or click on "Activities" button, type some letters to search in your tasks, and the extension will displays results. The task editor will be open if you click on a task.

Calendar menu
The second feature bring with the extension is the calendar menu which can be open by clicking on the date in the topbar. For now, the GTG calendar menu will replace the existing, synchornization of both is planned for the future. This menu can be split in two others, tasks menu and todo list.

Tasks menu

This menu shows GTG's tasks to do for selected day in calendar menu, on the left. You can see two different colors for your tasks. The first one (Grey) displays tasks which has start date identic to the day selected and the second one (Dark grey) displays only tasks with a start date before the day selected and/or a due date after the day selected.

Todo list

On the right side of the calendar menu is the todo list. This menu displays only tasks without start date AND without due date. By this way, every tasks are listed to user.


Plugin for GTG


This plugin add possibility to be notified about your tasks on GTG.

* Download archive, or clone repo
* Copy content on GTG plugins folder
* Active it on GTG


Open time picker
If you open task editor for a task, you'll se a new button ("Notification") When you click it, the time picker is opened.

Select time/date
Here you can chose a date/time to be notified for this task. Now you just have to confirm and an job will be remotly created with at command.

When job is executed, a python script ( will be lauch and notification will appear with "Edit" and "Done" button. For now, if GTG is closed when you click on one of the two buttons, nothing will happen so, GTG must stay open. If you click on "Edit" button, the task editor will be open for this task. If you click on "Done" button, the task will be mark as done on GTG.
