Additional Components / Widgets / Controls

I am evaluating Zoho Creator as a potential replacement for an old Delphi program, but Creator seems to be missing a number of controls and components that are to be found in other development tools. In particular, I'm looking for:
  1. A "Tabbed Notebook" or simple tab container on which I can place the Creator Rich Text control;
  2. A "Splitter" control;
  3. A "Tree Structure" component;
  4. A "Progress Bar" widget.
Is it possible to to obtain one or more of these from users of this forum or third parties?

Many thanks!

Steve
