Hey thanks for the report. There where some icons not visible. In the new release you find a star symbol on the right hand side of the dialog.
The project is still alive. The only problem is time. Since version 0.0.6 I didnt wrote any devlogs, because of the lack of new features. The most updates were bugfixes and performance ones. Currently I prepare everything for an open source release (Writting documentation, get a stable api of the underlying library). But I will announce the open source release as devlog.
