Wa Alaikumassalaam wr,
Thanks for the comments. They will be fixed before final 1.1.0 release.
Ahmed, that indexing bug (which created .zekr in current user home regardless of -workspace option) is also fixed in 1.1.0m1 release.
In recent versions of SWT (from 3.7.0 on), it first searches for existence of WebKitGtk, if not found tries for Mozilla XULRunner. You may specify which browser to use by using this option: -Dorg.eclipse.swt.browser.DefaultType=mozilla/webkit
