Module development and code questions

Weblink should have a default option to open links in a new window. Users now have to change this option manually. I think admins should have control over the default value.

Also I need to know if someone could code this module to not only open new windows, but open them with a frame in the top. In this frame I wish to add my site info as the referrer. This way anyone that hotlinks to content on my site would have to show where it originated from. I know this can be altered, but the general public wouldn't bother showing the real url.

I want to use popup windows in some of the module development I'm beginning to work on, but I can't figure out how to take advantage of the Drupal system itself in a popup window...

For example, I have an image gallery page that opens a popup window when a user clicks a picture, but the content of the window is generated by a separate, standalone PHP file (popup.php) not by the Drupal system (index.php). If I want to add features to the popup, like a rating system, a title from the database, etc, it would be a lot easier to have the popup page integrated with Drupal.

There are times when I want a module to display nodes in alphabetical order by ascending title rather than by created date descending. So I hacked my taxonomy.module to let me send sort field and sort order paramaters to my taxonomy_select_nodes function calls. I've blogged it on urlgreyhot.

So I want to know if this is a bad thing? If not, can CVS HEAD be modified to include this change?

Does anyone have a module for creating OPML file of your import module feeds? I'm thinking of creating one so I can export my feeds to NetNewsWire and share with others on my site, but don't want to re-create work if anyone else has done it.

I have an idea for a block modification that I think others might find useful. The best way for me to describe it is via a description of what I would like to see. Here goes:

My web host allows me to configure up to X mailboxes associated with my domain name. I want to assign these mailboxes to a subset of my site's registered users (e.g., username@mydomain.com, where "username" is the same as the user's registered name on my website --BTW, I expect to manually create these email accounts using the webhost email admin tools). I then want to allow these select users to access my webhost's webmail login page from a link within the navigation block (preferrably directly above the "administer" link).

I don't wan't anything fancy like auto-login; I just want the user to be taken:

(a) to a static page with a frame that displays the webmail login form. Or,

(b) directly to the webmail login page.

So far, I have created a special role for individuals that I want to assign a username@mydomain.com email to. However, I don't know where to start to implement the desired changes to the Navigation block, or creation of the associated static page/frameset, and linking it to the Navigation block code (Perhaps because I am an absolute newbie, with no business even thinking about these kinds of changes).

So, what do you all think? Does this functionality exist somewhere already? If not, how difficult is it to implement, and where should I start? Thx,
