Having been deeply involved with the evolvement of FMEDIT2001 ( take a look) I respectfully suggest you consider any or all of the following:
CALCULATOR
ABILITY TO READ WORD DOCUMENTS
ABILITY TO READ EXCEL DOCUMENTS
ABILITY TO READ PDF DOCUMENTS
When you install FULL version of Servant Salamander 2.5 RC1, there is Eroiica Viewer plugin available. To display DOC/XLS/PDF document, focus it in Servant Salamander panel and press the F3 key (Files > View command).
