Hide Download files page (IDP)?

Question

I use "Inno download plugin" in my inno installer, I wish to download the files before I get to "wpInstalling" and to hide the IDP download page, Now here is the problems I encountered:

1. If I use "idpAddFile" function i must specify "idpDownloadAfter" and thus i cant hide the IDP download page from the user
2. If i use "idpDownloadFile" function my inno setup becomes "slaggy" and slow for some strange reason
