### Describe the new feature

I have a request to add an option to be able to manually determine the order in which programs are installed.

I created my program package, but I can't set the order in which the program will be installed. For example: I would like the VPN to be installed first for privacy reasons, then the antivirus for security, and then the other programs.

Currently UniGetUI installs programs for me in alphabetical order which is a problem. Because, for example, in order to install Handbrake, I first have to install Microsoft .NET Desktop Runtime 8.0, this is just one example surely there are more such.

It's the same with Python. I have various programs written in Python, some of them will install before installing Python itself by the fact that I can't change the order of installation.

### Describe how this new feature could help users

Such an option will help people who want to automate the process of installing programs and reduce as much as possible, manually installing programs
