I am using Eclipse Neon.3 (4.6.3). In the past, Eclipse used to have several tabs on the bottom of the editor window, when a file was opened in the Properties File Editor mode. There you could choose to view the file either in a table-like view or as a plain text file.
I usually edit my resource files in plain text, which still works fine. However, the table view had one nice feature: Duplicate entries were highlighted in red color in the table-view.
But this view is no longer available, since there are no tabs in the Properties File Editor anymore. Did I miss anything? Where has this tab gone? Do I need an additional plug-in for this feature? As far as I can tell, this used to be a built-in feature of Eclipse.
