If you'd like to see a certain feature added sooner rather than later, please consider rating it, as it will motivate me to push out updates more often! Thank you.
The list below can be viewed as a roadmap for Inventool. The lower the number, the more likely it will be available in the next update.
1. Blocks for UITK
Inventool originally supported both uGUI and UI Toolkit (UITK). Support for UITK has not yet been implemented in the new Blocks system, but it is planned for a future update.
Wow, I guess nothing else is planned at this time! Feel free to request something.
