Here are two lines that I have changed for config.h:

[Java]       = { { .i = 0 }, },
[JavaScript] = { { .i = 0 }, },

My idea was to remove something unnecessary, so I made a patch and a portion of some lines for the package builder script, including differences.

rm ROX-Filer/ROX/MIME/application*{msword,pdf,ms,realmedia,stardivision,sun,x-{deb,ja,rpm}}*.png || true
rm ROX-Filer/ROX/MIME/audio*realaudio*.png || true
rm ROX-Filer/ROX/MIME/text-x-java.png || true
rm ROX-Filer/ROX/MIME/video-quicktime.png || true

With the system.twmrc file:

twm: unable to open fontset "-adobe-helvetica-bold-r-normal--*-120-*-*-*-*-*-*"

With the blanked .twmrc file:

twm: unable to open fontset "-*-helvetica-bold-r-normal-*-*-120-*-*-*-*-iso8859-1"

I made a patch to change the default font to fixed entirely.

I also made a system.twmrc file as the rebranding to replace the original one to make twm look better. The original one was dull and messy. For example, the icons for modern applications in the minimized state had become garbled in monochrome. Here are two screencaps comparing how they look with the default font change.

This issue needs to replace all $dir with $d because $dir resulted in an empty output, and Xenocara/X11 couldn’t handle reloading fonts, causing some apps like twm to break. find has also been simplified.

I’ve noticed some of the entries contain references for manuals, menus, and hotkeys. Before solving any issues, find those strings and replace or remove them.

I searched these strings:
* firefox
* google
* google-chrome
* systemd

Found affected files:
* lib/keys.in
* man/icewm.pod
* man/icewm-keys.pod
* man/icewm-preferences.pod
* man/icewm-toolbar.pod
* man/icewm-winoptions.pod
* src/default.h
