Each block has a unique set of options but Greenshift uses a component system so there are common panels for most of the blocks. Panels can be accessed from the Inspector and from the Toolbar. They are available only when you click on the block.
All options are available in Inspector (sidebar), there are some panels (spacing, typography/background) that are available in the toolbar so you can access them more easily. Some blocks (for example, advanced buttons) can have more quick panels in toolbar.
All blocks have special Icon “A” in toolbar with quick access to most commonly used options

When you change an option, the panel will have a blue dot which will indicate that there are some changed options that are different from the default.
Each panel has a clean button in end where you can clean all values for current panel. You can also clean all design values in block, for this, click on Brush icon in toolbar and select to clean all styles.

All blocks have some unique relevant panels and common design panels. Beginner blocks have separate logical panels, Professional blocks have common “Local Style” panel. Check the difference between a beginner and a professional

Using panels is simple, just open section and add changes in fields. You can see also that many values have some helpers, they are styled as small buttons (Presets, classes, fluids, underline effect, etc). They will help you to add some ready presets or extended values

In numeric fields, you can click on right mouse to enable Variable selector or add string values instead of numeric
