I think the issue here is Jonathan and John are trying to see it from
the ordinary user's perspective, whereas Andreas and Tim are coming at
it primarily from a developer/designer perspective. As developers we
tend to look for "the nicest solution" within our very logical
understanding of the application's framework. We have a pretty clear
understanding of how the application is supposed to work so a lot of
user errors don't make much sense to us. The ordinary user, however, is
"attempting to do a task, getting there by imperfect approximations.
Don't think of the user as making errors; think of the actions as
approximations of what is desired." [1: Norman, 2002] Good application
design encourages the user to explore and discover, and tries not to
severely punish them for making errors.

The problem is, your ordinary user doesn't have as clear an understanding of
all this. We all know that users do many "stupid" things which we can't quite
imagine. But at the time the user does it, their action does seem logical to
them. We should not punish them: a deleted Bible could be very difficult to
replace 30mins before a service (whereas a deleted song can easily be retyped
fairly quickly).

The problem here is not that the dialog isn't clear enough, it's that many
(Windows) users have been "trained" to ignore such confirmation dialogs. For
example, whenever a user deletes a file on Windows, they have to say yes to a
confirmation dialog. But many users are so used to clicking yes on such
dialogs, they do so automatically ("muscle memory") before they even think
about what they've done. That's one reason the Windows Recycle Bin is so well
used!

I agree the edit icon is not very well placed. Have a look at the row of icons
there: "Edit the selected Bible", "Delete the selected Bible", "Preview the
selected Bible", "Send the selected Bible live", "Add the selected Bible to the
service". Now that is confusing! The first two act on the Bible itself, but the
last three act only on the selected verses. This is very different to the Songs
manager, where all five of those icons act on the selected item.
The cleanest solution, IMO, would be to change the Bible Editor to Bible
Maintenance. This would reflect the Songs manager where we have a "Song
Maintenance" form for managing Authors, Topics, and Song Books. It would also
then be very logical to have the "delete Bible" functionality within the Bible
Maintenance form.

Title:
Bible delete button is too accessible
Status in OpenLP - Worship Presentation Software:
Opinion
Bug description:
The ability to edit Bible meta-data and delete Bibles was recently
added to the Bible plugin. There is now a "Delete the selected Bible"
on the Bible plugin toolbar. I think this is far too
accessible/visible for what is a non-reversible (no "undo") and
therefore "dangerous" operation. Would be much safer if moved to
inside the "Edit Bible" dialog.
