1. Browsing www requires heaps of ram these days, OWB is pretty outdated and the current hardware is ~10yrs old which doesn't help either.

2. Personally I don't bother with .info too much. Set the parent window as a lister, show all files and snapshot it (preferably for volume, make sure you have a disk.info there). You can do the same for "My MorphOS" view.

5. rxcmd OWB.1 HIDE. For custom hotkeys I use MMKeyboard, though for mouse you have to do it via Poseidon settings, also Ambient screenbar menu is nice for command + key. For general hotkeys check IControl settings and Ambient hotkeys.

8. For ADF images it's pretty straightforward ("Run >NIL: SYS:Tools/e-uae/e-uae -f SYS:Tools/e-uae/conf/A1200.conf -0 %sp" in Ambient's MIME action settings), for WHD games some more work is needed, for example - https://morph.zone/modules/newbb_plus/viewtopic.php?topic_id=12013&forum=3#131131
