Come on, calm down just a little…

You can call it advertising if the intention is selling something -- which intention I definitely don't have.
Oh well… 
Of course I didn't mean to and didn't express any "threatening" to anyone. What I said simply was "this feature [is so important to me that it] could make me move on to another product.
This is because it is my strong conviction that said feature
"re-arrange the sort order of files
in details mode with the mouse and keep
this custom sort order in between sessions"
is an absolute killer feature for professional electronic document management. It already has proven to be a killer in "slide" programs like Google Picasa and FastStone ImageViewer, and it will also be there in the next version of a not-so well known file manager from Cologne...

This is VERY well-known to me, and I'm quite sure that my feature request qualified like so from the very beginning. Of course I have sent this feature request also directly to the developers, as I have been doing since 2003.
For example, I've suggested the ActiveX viewer and floating tooltip thumbnails in July 2003, PDF thumbnail generation and b/w tiff file preview antialiasing in April 2004, as well as the new File Filter Control Field in April 2005 --- to name but a few feature requests I had handed directly to, and discussed at length, with the developers. Not to mention that these feature requests actually have been implemented in the software 8).
Cheers,

PS: Here's some more yet to come: 
8) 8) 8)
[ul][li]The new "File Filter Control" seems not to work when switching to Flat View™.[/li]
[li]Make the normal find dialog usable as well inside file collections.[/li]
[li]How about the possibility to search for files "inside previous search results"![/li]
[li]Possibility to search for occurrences of text inside preview pane while html/mht-document is being displayed.[/li]
[li]*.eml file preview seemingly not working although *.eml-files are equivalent to *.mht-files, preview of which does work. [resolved][/li]
[li]When copying/moving files by dragging them over toolbar buttons, cursor "+" sign and copy/move behaviour seems not always consistent[/li]
[li]Automatically highlight first occurrence of search term when searching for text inside the preview pane![/li]
[li]Even better: "Find-as-you type"-highlighting (as in Mozilla Firefox Browser) when searching for text inside the preview pane: just by starting to type on the keyboard while preview pane has the input focus. Killer feature![/li]
[li]Different thumbnail sizes when lister in Thumbnail View Mode (here: smaller thumbnails for better overview) as compared to when lister in Details View Mode (here: very large floating thumbnail preview inside the tooltip for better recognition of file contents).[/li]
[li]Suppress preview generation inside the preview pane (because it slows down the opening of large files) when the respective file is being double clicked in the lister.[/li]
[li]Enable Ctrl+C for "Copy" inside the preview pane for all file types.[/li]
[li]Enable placement of preview pane separately on second monitor (as a separate window that can be maximized).[/li]
[li]It seems not possible to assign (multipage) TIFF with an external ActiveX viewer (e.g. AlternaTIFF) inside the preview pane, although the respective viewer is there and working. Dopus instead still continues to use its internal TIFF viewer[/li]
[li]Possibility to set the sort order of folders always alphabetically, even when file sort order is set to "sort by date".[/li][/ul]
