I really love koha, it has tons of features and a really nice interface. but it's kind of frustrating for me to see that all the html interface code is mixed with perl code (or the perl code mixed with html...). :) this way it's pretty hard to customize koha and give it your own "flavour". what about using some template-engine like HTML::Template? it's easy to use, fast and your code gets much cleaner. it would be also cool if there would be a global configuration file for system preferences like main currencies or membership categories. thanks for your hard work --Florian
