This bookmark manager entirely written in Gui4Cli (Dimitris Keletsekis) for OWB, NetSurf & IBrowse,  has its own way of doing things. Read them in the OWB_.gc  script in the 'Textfile's  (or see below)
Hope you like them, but let me know what you don't like, or want 
 JosDuchIt JDuch&fulladsl.be
Responsibility taken: None

The essential Gui4Cli files are included. (The Gui4Cli interpreter for OS4 occasionally spits some comments. Those will be removed, but since they don't bother me too much, not before i get some feedback. )
Doubleclicking  on the LnchArchOWB icon will open the GUI, ask you where your browsers are stored, and launch OWB.
The <?> button explains what you can expect (if you did not read the source)
The script is launched in Debug mode. You can edit LnchArchOWB to launch in normal mode.

I hope the authors of NetSurf and OWB will take note of my main requests for a better version;
1) arexx commands for resizing and positioning the window.
2) arexx commands that permit to address the individual tabs, know how many are open, which ones,  not only by number (as in IBrowse) but  also by position (first, last previous, next)
