I found TrakAX – you can create audio within this programme and then bring it over to work with Slide Effect.
The FONT thing is overcome partially with PICNIK – a free Image Editor that has some great features for creative folks. It is wysiwyg and so easy to use!
I also found SwapSamples.com another free sound site.
You can pay a donation and get a great fast download pass for a year.
.. am so looking forward to 2010 enhancements in Slide Effect – yeeeah!
