Hi, I am very pleased that you are also supporting LibreOffice on PortableApps.com ! And it's very nice you provide us with a multi-lingual version. But I do have some issues with it, and ofcourse they were to be expected. It's not criticism but please see it as feedback for improvements.
1) LibreOffice is much slower starting up then OpenOffice. I don't know why since it is based on OpenOffice.
I like to report on my findings while upgrading LibreOffice 3.3.1 to 3.3.2 :
2) The progress bar of the PortableApps installer doesn't show any progress while removing packages of the old LibreOffice version. This must be a bug.
3) LibreOffice has problems with long path names. I know this is known, but it causes LibreOffice not to be able to read templates. The content of any folder below data > settings > user > template > 'category name' will not be red. I tackled this problem myself by cutting/pasting the content of sub-folders (templates) into the folder up one higher.
4) The experimental option to have the installer only upgrade the default English plus your selected local language and thereby saving 200 MB disk-space worked very well, it did just that. No problems.
That's all I have for report, so on the whole that isn't much at all considering the size of LibreOffice !
