The Inspector is where you find your canvas presets, alignment tools, timeline settings, effects, utilities, edit modes and more
Understanding the Inspector
Stretching from top to bottom on the right of your editor window, is your Inspector.
When an item is selected in the bottom left layers list, a panel of options will appear in your Inspector to reflect applied attributes. Options will differ depending on what is selected.
The right Inspector reacts to what layer you have selected
Removing a block from the Inspector
To remove a block that has been applied to a layer, you can either toggle-off the effect or have the block highlighted and hit "delete" or "backspace" on your keyboard.
