AbiWord on Maemo
AbiWord on Maemo is basically AbiWord with some UI adjustements to fit on a tablet device. This will explain the difference from a development point of view.
The problem is the size of the screen.
No status bar, no rulers, one toolbar.
AbiWord as far too many options to reasonably fit on the estate provided by the small screen. It is a pocket device after all. So a good set of menu items have been removed.
Also with only one toolbar, the content have to be simplified to the strict minimum.
The toolbar layout is declared in src/wp/ap/xp/ap_TB_Layouts_SimpleOps.h
