This is the window that contains the Canvas (Fig. 1). Since you can have several Canvas windows open, above them is the Canvas switching tab, where you can quickly switch from one window to another simply by touching the label of the Canvas you are interested in.

- the Title bar contains some information about the file being processed (name, canvas size, page size, resolution and zoom level), the version of CSP in use (PRO or EX) and the classic Minimize, Maximize and Close buttons;

- the Menu bar is similar to those found in almost all programmes, i.e. a series of drop-down menus containing the programme commands.

By clicking the Shift + Tab key combination several times in succession, first the Title bar disappears, then the Menu bar disappears, and finally both reappear.

The Command bar, the set of icons above the Canvas (Fig. 1) that give direct access to certain commands, is also customisable.

To add or remove commands to the Command bar, go to File > Command Bar Settings... or right-click on the Command Bar and select Command Bar Settings...

For example, to add buttons for horizontal and vertical flips of the view (similar to those found in the Navigator), go down to View > Rotate/Invert and choose the two buttons.

Select the chosen command and click Add, or drag it onto the bar, wherever you want.

My current Command bar (I have divided it into two rows, otherwise the icons come out too small):

You can also add subtools to the Command Bar: that's what I did by adding the Select layer command (formerly Layer selection, as it continues to be called in my CSP), which I find very useful for figuring out which layer a part of the drawing is on without having to scroll through them all. After activating the Command Bar Settings window, I chose Tools from the drop-down menu, scrolled down to Select (in my CSP, perhaps it's Operation normally) and dragged the command onto the Command bar.

I put the Open Clip Studio button and the Duplicate Layer on the Command bar; I moved the Colour wheel, putting its icon on the Command bar by selecting it from Command Bar Settings > Window > Colour Wheel and making it float.

On the left-hand side of the interface, placed vertically, is the Tool palette (Fig.6), i.e. CSP's toolbox; this is perhaps the palette that is used the most, especially when you do not yet prefer to group tools elsewhere (but then again...). In this column are grouped, by type of function, the most frequently used CSP tools: this is where you go to browse brushes, activate the selection tool, choose balloons, etc.

Immediately to the right of the Tool palette I find two other palettes, which are essentially its extensions, the areas where I go to refine my choice of tool: the Sub Tool palette and the Tool property palette (see Fig. 1).

In the Sub Tool palette you choose, among various tools grouped by function affinity, the one that suits you best: a G-pen or Calligraphy brush, a light pencil or a technique, a fill, a balloon or a text.

In the Tool property palette you can go and modify the parameters that characterise the chosen tool, so you can set a certain response to pen pressure or the opacity of the stroke; the thickness of a vignette or the radius of curvature of its corners, and so on.

At the bottom of the Tool palette are the colour icons (Fig. 7). There are three of them, the Main colour (1 - Main colour), the Sub colour (2 - Sub colour) and the Transparent colour (3 - Transparency).

X = alternate between Main colour (Main colour, 1) and Sub colour (Sub colour, 2);

C = alternate between Transparent colour (Transparent colour, 3) and the one between Main and Sub colour that was previously selected.
