New build of LazyCure was released and available for testing. Comparing with LazyCure 3.1.2 it contains some fixes and code improvements. Functionality to save and load tasks was implemented. It is recommended to upgrade to 3.1.3 version only if you are going to use Tasks functionality in future. However, ability to display time spend for specific task is a matter of 3.2 release, so you can continue using your current version and wait for 3.2.
You can download LazyCure 3.1.3 installation as zip-archive from this link or from Download page.
