Yes of course you can download any mod, addon or map that you want and update it.
My application allows you to launch mods, addons and maps easily. And through the content explorer you can access hundreds of elements easily.
But all these contents are not developed by me, each mod, addon and map belongs to different developers.
Check links section to access the most useful community's websites for get any update or new content.
If you want to create your own presets it is very simple after having made a selection of mods, addons and/or maps, you just need to access to selected files panel and use the button in the lower right corner to save the selection as a preset.
The preset configuration window will be displayed, where you can add a title/name and select the type of configuration (category), you can also modify the selection made and add a custom image or select one by default.
As configuration type or category you can write any value and this will create an automatic filter in the presets panel.
You have all this information on help panel
Use F1 or last right button on main toolbar to access the help panel.
