Prompt before install + installation folder

Currently, the Windows installer when executed, installs Logseq immediately. It does not prompt the user to specify the installation path. This is problematic for three reasons:

  1. The user is not aware of where the program is installed.
  2. This behaviour is atypical - most installers have a welcome screen, the user has the option of cancelling the installation.
  3. The user may want to install the program outside the userspace

The installer should ideally prompt the user to pick a folder
