My context menu on my solution explorer is way too long, although I am not complaining, this is due to the fact that I have a lot of extensions installed. Most commands I can find... but there is one pesky command that always is difficult to spot and I use it all the time.
"Set as Startup Project"
Is there a way (or an extension) that allows me to add a sub menu to the context menu for commands I use regularly or an extension for adding a toolbar on the solution window?
It doesn't require an extension, you can alter the menu to your heart's content without coding. Use Tools > Customize > Commands tab. Click the Toolbar radio button and select "Context Menus | Project and Solution Context Menus | Solution". You should see your too-long context menu. Move a favorite command in a better spot with the Move Up button. Use the Add New Menu button to add a sub-menu.
