Ok, thanks guys, barcodes are off the list for version 2.0.
The labels in 1.5 are pretty basic, but I built a solid foundation for really improving them, I use it a lot already. In 2.0 here will be a variety of types and sizes to choose from an the ability to underlay your own images under the text. Still in planning phase but I expect to coding it in a few weeks.
The notifications work well (better in 1.5) and I have plans to continue to optimize this feature as I rely on it myself to keep up with my small brewery.
I also plan on improving the photo feature as I like to see my brews at various stages.
Also, I'm thinking of adding a temperature field so you can record the temp at which fermentation took place.
Lastly, the ability to add and remove steps (currently fixed to 4) might even make it in a pre-2.0 version as I'm finding that 4 steps just isn't enough for complex recipes.
