Here’s a GitHub project for an OmegaT plugin that converts URL’s in notes and comments into clickable items that open the URL’s in the default browser. Pretty neat, especially when you’re working in a team project and need to insert references for the editor or another translator.
In order to install the plugin one needs to create a folder named LinkBuilder (or whatever sounds good and preferably makes sense) inside plugins subfolder either in the OmegaT installation folder, or in OmegaT settings folder, download the latest release, and unzip it into the newly created LinkBuilder folder. The plugin will be activated upon OmegaT restart (or in a new OmegaT instance).
I don’t know who the author of the plugin is (other than his username at GitHub is hiohiohio), but kudos anyway!!!
