I am new to Blender and loving it. I have a request for a feature that at least for me would be a huge asset. I would like to have the ability to select from different startup files. Right now my only choice is to save current or load factory settings. I have different workflows that would benefit from having the ability to easily swap out what startup configuration I need for what ever I am doing. Currently the only way I have found to do this is to create my config folder backup, save it to a different location and then swap them out based on my needs. So where would I properly post this request?
Blender has a feature called Application Templates, which allow you to create custom re-usable project configurations tailored to your needs.
In order to create your own Application Template, you need to create a .blend project with the interface configurations that you like and optionally a Python script which is executed when the startup file is loaded. For detailed instructions see the following answer on Blender's StackExchange.
Existing Application Templates can be used to create a new project using File > New in Blender.
Not sure if this is what you are looking for, but, there are some workspaces that you can customize according to your needs. If that's not the case, go to https://blender.community/c/rightclickselect/
