when I debug a word in proofing tool for example (كتاب)
the detailed display of this word begins to appear as follows:
baa-arab.fina
teh-arab medi
kaf-arab.init
I want the simultaneous display to start with:
kaf-arab.init
teh-arab.medi
baa-arab.fina
thank you

The proofing tool will show how the shaping engine works. In general lookups will be processed in the order they are stored in the font, but there are numerous exceptions that are processed based on the feature they are in.

Topographical features and their lookups follow this static order:

IsolatedForms
TerminalForms
TerminalForms2
TerminalForms3
MedialForms
MedialForms2
InitialForms

If this is not what you meant, then please provide a screenshot.

please watch this video in the link below, especially from minute 01:30 to minute: 04:04 where the connection of characters is of the following order:
isolated form;
initial form;
mediform;
final form.
respecting the meaning of Arabic writing: from right to left
