Separate Log Tabs per Directory
Instead of having a single tab with all the event information for all monitored directories, you could have multiple tabs per directory being monitored, each displaying only the events for that directory. Each tab will also have a number in the header to display the number of events that have been captured by that directory.

The fundamentals of this feature have been added to the Grid Log plugin in v2.7.0.7.
The Grid Log allows you to group by any column (drag column to the header grouping bar) and events in each group are counted with a number in brackets next to the grouping name. Each group is collapsible and you get a much better overview of each directory’s events.
For this feature specifically you can just group by
the “Directory” column. Note that this column may be hidden so you can show it by right-clicking on the header bar and selecting “Choose Columns”.
