I provided the link to Sketchucation Tools in my post above.
It is similar to the Extension Warehouse and Extension Manager. When you open the Extension Store and sign in with your SCF credentials, you will see a list of recent extensions.
You can click on the magnifying glass at the bottom to search for specific extensions, choose an author from the list and so on. If there are extensions due for updating, that will be indicated near the top of the panel. Click on the gear icon to see which ones need updating and to update them.
Click on Downloads to see what extensions you’ve downloaded, Profile to see your SCF profile, Bundles to see and install the bundles or extensions you have. Note that Bundles are only created for extensions you download from SCF using the tool. At this point it wouldn’t know about your installation of Bolt Maker although you could reinstall it via the SCF Tools tool to add it.
