Version 1.8 is more of a spit and polish update that includes several improvements and optimizations in addition to some new and lovely features.
One of the most significant changes to this edition has to be the Project Filters, which allow you to easily discover any task you're searching for in a few simple steps.
The Project Settings have been updated as well and got some new settings such as defining the default time span duration and a new section dedicated to task statuses.
App settings was redesigned from the ground up to be more user-friendly and well-organized. The options were divided into many tabs while retaining a basic grouping and providing additional information to help you navigate through each choice.
These are just a few of the things we've added to this awesome version. You can see the complete list of changes in the updates sections.
