User Reviews

Users appreciate TMetric's seamless integration with daily services, convenient timer use, and responsive developers. However, common issues include lack of clear timer indication in the UI, mandatory sign-up, and limited task management features such as inability to pull existing tasks and defaulting task names to browser tab titles without customization. These points highlight areas where usability could be improved despite the add-on's positive overall reception.

Pros

Seamless integration with commonly used services enhances usability.
Convenient timer functionality without needing to open a separate tab.
Fast response from developers including quick bug fixes.
The extension is generally well-received and recommended by users.
The service itself is highly rated, which positively influences user perception of the add-on.

Cons

The extension requires signing up, which some users dislike.
Lack of visibility for running timers in the browser UI beyond a colored icon.
No functionality to pull existing task titles from the database, leading to manual entry and possible errors.
Default usage of current browser tab title as task name lacks customization options.
Limited support for certain features, e.g., GitLab 'task' types instead of just 'issue'.

Nice! What I miss: 1. Support for "task" type of GitLab (not just "issue"). 2. Display the start/stop button in the sidebar of GitLab issue, instead of the header!

High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
