New feature: a text filter interface was added to the Output panel. It can be controlled via these buttons:

The first button makes the text filter bar visible, while the second one shows the context menu of the text filter. The text filter is defined by a regular expression and runs the UNIX grep command to perform the actual filtering of the output file. It can be used in two modes:

• match: in this mode only the lines matching the regular expression are shown
• no match: in this mode only the lines not matching the regular expression are shown

To run the filter type in the regular expression into the text line editor and press enter. When there are marching lines in the output the regular expression editor and the filter icon turn green

otherwise they turn red.

To clear the filter just clear the regular expression editor or choose the Clear filter action from the context menu.

The filter remains active when switching between output files and selecting new nodes. It also remains active when the text filter bar is closed. In this case its colour and tooltip tells us about the current filter being applied.

The actual filter can be saved and then loaded using the filter context menu. To manage the saved filters start up the Text Filter Manager dialogue from the context menu.
