Understood but that is a larger target than any single button or single menu item which are used all throughout Sigil. And more importantly there is already an AddExisting menu for people who want or prefer to access the menu with a keyboard. So no functionality is lost.

I sincerely doubt people with any hand motor disability would opt to use the drag and drop approach given they already have a way to AddExisting files in Sigil they can use. And luckily it fits into an unused area on the status bar so no screen real estate is lost. So I do not see a downside.

Please note, I am not forcing people to forgo their long established patterns of use, I am just trying to give people who prefer drag and drop an option with no or limited downsides. No one is forcing anyone to use drag and drop.

And your situation is why I just added the Change Reading Order dialog that can be used effectively without a mouse to augment BookBrowser's Drag and Drop interface for reordering the spine as it was mouse only. Having both methods can only help.

But let's hear what others think.
