=== Easier tasks ===
 +
 
 +
* Easier use of [[pg_dump when upgrading PostgreSQL]] (or ideally, invisible use of this, is both PostgreSQL versions are installed).
 +
* '''GUI for configuring a central postgres server.
 +
:* For instance, creating the [[Initial_Postgres_Configuration|initial user]]''', after asking for the root password.
 +
:* This can be a completely separate program. It can be in any programming language (Python with pygtk might be appropriate).
 +
:* It should parse the postgres configuration files, and then change them where necessary.
 +
:* To ask for, and gain, root (or superuser) rights, do whatever synaptic or gnome-system-tools does. There is commented-out code to get root rights in this way already, in connectionpool.cc
 +
* '''Warn when deleting used fields and relationships''': If a field or relationship is on a layout or report, or a field is in a relationship, warn before deleting.
 +
:* Create a new warning dialog in the Glade file, and create a C++ class for it.
 +
:* Add methods to the Document_Glom class, such as bool get_field_used(). Extra output parameters could return a string describing the use, or specific information about the layout, relationship, report, etc, on which it is used.
 +
:* Whenever the UI allows someone to delete one of these things, call the method and show a dialog if necessary.
 +
:* Depending on the dialog response, continue or cancel the deletion.
  
 
* '''Quickly add Relationship/Field''': For instance, when adding a field to a layout, quickly add a relationship so that you can add a field from it, without closing the layout window, opening the relationships window, and opening the layout window again. Or to quickly add a field to the current table when adding a field to the layout dialog. Or, when specifying a related choices lists (in a Field'a default formatting). (30 hours)

Or to quickly add a field to the current table when adding a field to the layout dialog. Or, when specifying a related choices lists (in a Field'a default formatting). (30 hours)
* '''Automatic Server Detection''': Patch postgres to use avahi for ZeroConf/Bonjour/Rendezvous service broadcast. Postgres already uses Bonjour on MacOS X.   
+
:* Add buttons to the dialogs in Glade.
* '''Deal with lots of data''' The custom tree model should progressively gets only the record values that are visible in the scrolled window, but I am not sure if libgda has already requested the entire result set. The new libgda API might be better.
+
:* Create signal handlers for those buttons in the dialog classes.
* '''Custom Print Layout''': For instance, a perfect-looking official invoice. Implement with CSS fixed positioning? '''Time''': 80 hours.
+
:* In the button signal handlers, open the appropriate dialogs - see the code that does the same from the regular menu signal handlers. Then update the current dialog to show the new available choices.
 +
:* Ideally, think of a way to avoid this causing so many windows to be open at once, on top of each other.

* '''Scripting''': Most common actions should be standard features without the awkwardness of scripting, but maybe we need some way via the custom buttons to, for instance, on Contacts details create a related Invoice and take you to the Invoice details. For this, we must just present a python API for some parts of the Glom structure in addition to the current record object. This requires knowledge of the '''Python C API''', which is used already for calculated fields. Alternatively, you may use '''boost::python''' if you are already familiar with it.
