To add to @stefano.menci’s comments, you can also choose when to import forms which will save you a small amount of time - but its quite small like mentioned above.
You are probably finding that you are getting unwanted server round trips with out knowing it.
Is it that your app is taking too long to load? if so, how long and what does the code look like.
Or is it that you don’t want to have the menu options in the side bar?
If you can give us a bit more information like the reason you don’t want to download all the forms or code snippets or a clone link that would be helpful.
If you can’t then I guess your best option is to try to clarify what the intended goal is first.
Either way, with a bit more information I am sure the community can help you get your intended result.
