We are continuously improving the tool and are grateful for feedback on existing features, bugs and suggestions on what to improve and suggestions for additional features Thanks! ----- *Usage guide* Starting up - Download and enable the extension - Go to your signed-in Google Calendar session - Press “T” to enable the Chalk panel on the right hand side. This will switch to the current day/week (Batch) Color coding - In the “Colors” section on the top of the panel, click a color to activate it. A black frame around the activated color will appear - Click an existing time slot in your calendar to assign the activated color to it. This can be done quickly for multiple time slots (batch color coding) - A delay of a few seconds in the color switch is to be expected. Press the refresh shortcut (“command+r” on mac) to expedite the color switch - Creating a new time slot with a color activated will not change the color of that new slot Press “Esc” to deactivate the color, or press on a different color to activate it - Note: You can also right-click on a time slot to recolor it (and the color will be recognized by Chalk’s time tracking feature - see below), but this process is significantly streamlined by Chalk. The right-click method might be still preferable when you want to color each instance of a recurring time slot. Color labeling - In the “Colors” section on the top of the panel, double click on a color to rename it; confirm the renaming by pressing “Enter” - Click “hide” next to a color to hide it; click “unhide” to unhide all hidden colors Time tracking - In the “Summary” section on the bottom of the panel, click the “From:” and “To:” fields to activate a selection field for the time tracking time range. You can also type in custom dates - Press “”Reset to current week” to switch back to the current week time frame The table indicates the time spent per category Chalks icons created by Freepik - Flaticon (https://www.flaticon.com/free-icons/chalks)
