In this update:

Search bars

You can now filter your items/categories and properties.

Editing custom properties

You can now edit custom properties after creating them. You can now also name values just as you would properties and categories (by double-clicking).

Backwards compatibility notice:

Due to some structural changes, when opening projects saved in previous versions (before 1.2), you may need to adjust a few things:

1. Name property types again.
2. Add IDs to your values if you hadn't (double-click to rename).
3.  Check Show ID if you want to see the value name while editing databases.
