An app that can make Haiku a little application richer on the end-user front is called KMyMoney. It is a C++ app and the source is available on SourceForge.Net. It comes with a GPL license and relies on the KDE interface.

This app is a Quicken / Money type program with QIF support included. The screen shots look quite impressive. I would love to see this as part of a HomeSuite, like Word/Excel/Access/Publisher/Powerpoint are an OfficeSuite.
For it to be fully useful for those who switch to Haiku, it would need the ability to download financial transactions from vendors (Bank/Broker/CreditCard) through a Direct or Web Connect to an institution. Quicken offers both, the former I believe uses proprietary methods and the latter uses generic scraping.
However, it is ready to use as is. If someone is willing to install this in Haiku and have it ready on release of v1.0, I am ready to contribute sponsorship dollars to Haiku.
One big issue with KMyMoney is exactly the KDE Interface, which is a lot more than interface these days: http://api.kde.org/cvs-api/kdelibs-apidocs/
To make KMyMoney work, you would have to first port most/all of KDE, which isn’t pea-sized, to BeOS/Haiku, with all the resulting duplication of services, and then you probably have to fix Linux-centric details in KMyMoney, and also port any other components it might depend on.
It’s not always as easy as it might seem. C++ programs are not portable just by being written in C++.
FWIW, one of the Haiku devs is making this application:

http://www.capitalbe.com/features.htm
I recognize the portability hurdles. This was the reason I mentioned KDE. I do not want a KDE/Linux implementation, but rather, a native implementation.
As a Quicken user, I want a fairly fleshed out financial app and I believe KMyMoney is one and that it would benefit Haiku to have such an app in its portfolio.
As a neophyte, I was unaware of the other developments or the Haiku site had an organized app repository.
What is the link to the Haiku app repository?
I have viewed the supplied links. CapitalBe is further along and I have contacted them passing along my interests. BeBits requires siginup just to contact the developer, that ain’t happening. However, neither one is a killer app, although the potential is there.
What is FWIW?
I believe CapitalBe is created by Haiku developer: Darkwyrm, is it not?
FWIW = For What It’s Worth
http://www.acronymfinder.com is a great site for looking up stuff like that in the future 
BeBits is the Haiku app repository. Most software that is currently available for BeOS, Zeta and Haiku is published on BeBits. It’s a respectable site. http://www.bebits.com/privacy It’s a good thing that BeBits don’t disclose email addresses without a person being logged in. I get way too much spam due to my email address being visible everywhere. If you want to communicate with the developers of the currently available applications you need a BeBits account. That’s more effective than using these forums.
About software that should be bundled; The general opinion of the Haiku developers is that as few applications as possible should be bundled and make up the base distribution of Haiku. KMyMoney is not a good match for inclusion since it relies on components (a KDE compatibility layer, or port) that are not available for BeOS/Haiku now, and will not be part of Haiku Release 1. Even CapitalBe is not very likely to be included. A native port of KMyMoney is equally non-essential. While you might benefit from it being bundled, somebody else will consider it bloat. People will still have to add the software they care about. It can’t all be bundled. Only the essentials of what constitutes an operating system should be part of Release 1, Release 2, and so on. This is of course a moving target, as people expect more and more of their computer (operating system) out-of-the-box, but Haiku is about less-is-more.
