The second part of the plugin manager is the downloading and installing tab: it groups all available plugins in the same table allowing for a fast selection and install.
The screenshot is available underneath. Currently there are only a few test plugins on the list used for testing purposes.
Now the plugin manager is finished. The plugins can be downloaded and incorporated into nomacs. So the first version of the plugin system is finished. It will still improve during the next week when also the first plugins will be developed.
