- handling of %%leftmargin, %%rightmargin, %%pagescale and %% directives in general
The explanation how in particular %%pagescale is implemented was VERY helpful. 
I noticed that %%pagescale works differently in MobileSheets and in the ChordPro program and could not understand what's going on. That's hopefully clarified for me now.
My main usage for ABC is integrating ABC sections into ChordPro files. In that case the page margins specified in Settings - Text File Settings - Page Margins are applied also to the ABC section. Margins per song are not possible (?). This is perfectly fine for my needs and fully sufficient.
Text File Settings - Page Margins currently have no effect on pure ABC files. I don't miss it and have no opinion on applying them also to ABC files. It would probably not be enough for Laurent anyway.
