I was using bookmark functionnality often in Komodo 8 for large files,
and I see 2 annoying regressions in Komodo 9 :
1 - I cannot click on the “bookmark line” on the left to toggle on/off a bookmark
2 - I cannot toggle bookmark on/off with the right-click menu
The only way I have found to set / unset a bookmark in Komodo Edit 9,
is to use the keyboard shortcut (Ctrl+F2) which is less convenient (IMHO)
