My first try with portable apps was a disaster because I had no idea that a group of such small programs would take so long to install. There was no way to stop when I needed to leave for class and doing so unfortunately broke the flash drive. On my second try I went to install a smaller list, and it still takes forever and now I today I was again in a situation where I had to let it finish or take it. I had to risk letting it get stolen and there was nothing I could do about it.
As it stands, using the app installer is very risky if I have even a few hours. Furthermore, the license agreements don't appear at the beginning so I can't even let it run alone. I have to babysit the installer which completely defeats the purpose of a bath install. And of course, while this is going on portable apps itself often freezes up and shows as "not responding" so I can't always open new apps while this is doing on.
What I would like to see is this: When installing multiple apps at once have the option to suspend the download or install. It could then just finish the one it's on and then keep track of what other ones it still has to do to be resumed later. That way I can safely remove the flash drive if I ever need to without messing anything up. I would also like to see the license agreements for all the apps moved to the beginning of the install operation where I can read and agree to each one before anything is installed.
