Problem Description:
Simple Scan works document based but most people seams to not expecting this.

If you edit an text document, you expect that is will be stored in one
file. It makes sense to enter a name for that file while storing it the
first time. Further it is clear that these stored file will be replace
by all incoming changes.

I believe that was  starting point for the application "Simple Scan".
That is not wrong but it is not what people seems think about an
application for scanning pictures and documents.

A scanning application is not an editor. You want scan pages, arrange
them and store them into a file. Most of the time you do not want to
place that file and if you want to explicitly say that.

Problem Steps:
- scan page A
- press save
- enter name of file and store
- delete scanned page
- scan new page B
- press save
- (oops previous stored page A is replaced by page B)

Solution:
- remove document binding
- replace the button "new document" by "clear all pages"
- replace the button "save" by "save as"
- remove menu-entry "save"

I uploaded the code to fix the problem as described with the commit 916.
Unfortunately I am not familiar with the launch-pad workflow and do not
see a way to send an pull request. May anyone help me with this.
Currently the code is at lp:~rdoering-info/simple-scan/simple-scan .

Thanks,
Robert

Title:
  Save button doesn't warn before overwriting existing file

Status in Simple Scan:
  Triaged

Bug description:
  Usability bug: In a typical serial scanning workflow, one tends to scan a document, click on the 'Save' icon, navigate to the location where the document should be stored, enter the name of the document and finally click on the 'Save' button. So far so good.
  After that, one typically moves on to the next document, which typically needs to be saved to a different file.
  Currently however, when scanning a second document, it is displayed next to the first. Other than that, there is no indication whatsoever that Simple Scan will overwrite the previously saved document as soon as the user clicks the 'Save' icon.

  So the user will typically remove the first page(s) which he/se
  presumes are safely stored in a file and hit 'Save' again...

  Moreover, if the user isn't paying close attention, he/she could run
  into the situation that numerous scans have been made and presumably
  saved, only for the user to find out that only the *last* scan was
  actually saved and all previous scans were overwritten.

  I've run into this 'bug' numerous times and so have other people in my environment who have been using the application in this manner.
  IMHO there are numerous ways to 'fix' this:
  1. Always warn before overwriting an existing document. In an application as simple as Simple Scan, I cannot imagine why anyone would want to have the 'Save' icon/button working the way it does now when scanning multiple documents.
  2. Clearly show which saved document the user is currently working on (e.g. display the file name in the menu bar).
  3. Find a way to make absolutely clear to the user (at the first use of the application?), that the workflow for serialized scanning of documents is using a 'CTRL+N' (for new document) after EACH scan.

  A combination of the above would of course also be a solution.
