Pixelpost is a technically mature, highly functional and reliable product, therefore future versions will probably see improvement in small details only.
Two things I would like to see:
- the ability to change colours, fonts and maybe the layout of the backend. It is not really important but would be nice.
- multiple blogs, browse and about pages.
In the past the developers have done a great job in not including too many features and gadgets. That's what plugins can be used for. Pixelpost is a tool for photoblogging and not a swiss army knife.
