o.o.gui.preferences.views.SaveOptionsPanel.java was modified without using NetBeans GUI editor, and design in SaveOptionsPanel.form and SaveOptionsPanel.java is diverted.
As a result, we lost a GUI to set "local external command configuration" from OmegaT UI.
Also we lost a dialog to enable "project specific external command".
There is preference key "Preferences.ALLOW_PROJECT_EXTERN_CMD". There is also allowProjectCmdCheckBox object in "SaveOptionPanel" class but now shown on dialog.
It seems to have happened when RFE#1695 Select output format for statistics output: JSON, XML or Text Pull-Request #675 has been merged or before.
I've tried to fix the issue at Pull-Request https://github.com/omegat-org/omegat/pull/924
There is also a missing UI to configure post-translate command in user level.
The bug is not affected in OmegaT 6.0 release. Please find an attachment that is a capture of OmegaT 6.0 dialog.
