This version allows you to fully customize shortcuts in menus or toolbars. You can also add your new toolbars with often used functions.
To start customizing, right-click anywhere on the menu or toolbar and select Customize.

A new customize window will appear. While this window is displayed you can customize the menu, toolbars or add/change shortcuts to tools.

In the example below we will add the Blur to Toolbar.
While the Customize window is open, go to tab Commands and find Blur in Categories, then select Blur in Commands list.

Now drag the Blur Item out of the window to toolbar:

Find a place in the toolbar and drop it there:

You can now right click on the Blur in the Toolbar and rename it, choose or edit icon for it. Of course you can leave it just text.
Note: You can grab whole submenu and place it on toolbar. For example in the Categories find Filters and then in commands drag the Blur > submenu to toolbar. This will place it as submenu to the toolbar:

New Toolbar
You can create new toolbar by simply clciking on the New in the Toolbars tab of Customize window.

This will create new empty toolbar where you can add your often used functions, instead of adding them to the Standard Toolbar.

Re-arrange toolbar
While the Customize window is open you can also re-arrange toolbars. To drop tool from toolbar simply drag it outside and release mouse.
Reset toolbars
If you want to reset all customization on a toolbar, go to tab Toolbars on Customize window, select Standard Toolbar and click Reset button.

Adding your own short-keys
You can set your own short-keys to the tools in the tab Keybord on the Customize window.
Tear-off menus
The sub-menus in Filter menu are tear-off. That means you can directly "tear-off" the menu and it becomes a toolbar.
To tear-off menu, click on the sub-menu grip and drag the menu out its place:

The tear-off toolbar will be created:

Note: The toolbar created this way is a copy of the sub-menu. the sub-menu still exist the same way.
This way, PhotoBrush will now let you to fully customize the interface to what you need.
