Did you give farr some time ? most of your suggestions are already implemented in some ways.
[edit :
yes, it seems slightly impolite or defensive. Sorry about that.]
>1. Simplify settings & options UI like launchy. In fact users do not care what a path's score is. So K.I.S.S ? LOL
There's already a beginner UI mode. I personally care about path score... Although the K.I.S.S. philopsophy is good at times, it's also good to be able to configure a software to your liking.
>2. Index registry "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths" so Launchy acts exactly as Win+R
farr already looks in all the right places so I wonder what positive change would that make. Could be interesting to implement... don,t know.
>3. Support indexing Google Bookmarks, Live bookmarks, Del.icio.us bookmarks
Did you look at the addons ? I don't use these , but Del.icio.us bookmarks are "supported"
>4. Support Opensearch like firefox do.(Something like Google Suggest)
There are already some plugins doing similar things.
>5. I strongly recommand "launchy"-like two-column UI design. On the left you type command, the right display program name, the middle display an icon. The advantage of this is, you can type 1+1 on the left while display 2 on the right. Another example: Left for word input right for spell check or dictionay? LOL.
I personally very much prefer farr's UI : you can see more info at once (creation date, path, etc.), not to mention, more results, if you wish. Much more precise. To browse directories, it's more convenient.
>6. Now the most intersting part, if user's input matches a file, and a icon appears, display Explorer menu when right click the icon. :-)
This is already the case & more. Have you tried it?
>7. When a exact file/folder matches, support drag & drop operations compatible with Explorer. e.g. I type C:\Tools\Notepad.exe and then drag 1.txt from desktop to FARR so FARR launch 1.txt with notepad.exe :-)
Some of that can be achieved. But can't you just double click on your txt file ????
>8. Index IE, Firefox, Opera history URL's & Webpage title
Much of that can already be achieved through addons, and just plain configuration.
>9. Options for store settings in Registry, .ini in %APPDATA% and in FARR directory to make FARR "portable"
Settings are already strore in an ini file in farr's directory. I don't know how portable it is though as I've never tried it on different machines.
>13. I strongly disagree using Ctrl+Space as the default FARR toggle hotkey cauz many CJK Windows use Ctrl+Space as default hotkey for IME switching
All hotkeys are customizable. IIRC Ctrl+space is the default toggle hotkey in many launchers (like Quicksilver).
