Kloker greatly extends Dfhack's old in-game labor manager with colorful features and integrated autolabor. The full personalities of dwarves, pets, visitors and enemies can be quickly browsed, sorted and subsorted. Their physical stats can be viewed, their best labors and abilities are highlighted and their problems are listed.
Custom professions can be saved and applied to other units in the batch actions screen. Dfhacks automatic labormanager plugin can even be applied momentarily to assign pending tasks between all or just a selected group of units.
Kloker centers on the grid of enabled labors like the original "manipulator" and also highlights certain strengths and weaknesses and displays detailed unit info. Options for level of highlighting, info and color theme can be set with hotkeys displayed in the footer.

old examples:
Here is an expedition leader automatically selected by embark profile, her description reveals she is "extremely fierce" with other good qualities, and respects combat, hates sacrifice but nobody's perfect. Seems a good choice for a captain ;

The summary lines are carefully formatted to not jump around while browsing through the list. The characters age and focus level are shown, their most useful liked items, dreams, priorities and gods. Also the characters traits are summarized in greater detail than in their long game description, using refined adjectives that indicate the in game effect of each trait.
Here is Nil Wheeledsyrups long description for comparison :
Mind and Body Attributes View: A characters mind and body attributes have a big effect on how well it performs at different jobs, and different jobs exercise and improve relevant attributes. (Military training is also good at improving some attributes)
In this view the attributes relevant to each job are highlighted white, but the next screenshot is focused on a cat and its climbing ability. The screenshots following this pompous cat show white highlighted attributes...
A characters mind and body attributes have a strong effect on the jobs/activities it can do best, so cavern keeper calculates "aptitude scores" and colors the activation grid to indicate the best and worst performing jobs. For the character and job in focus, the aptitude score is also printed along with experience and skill rating. See later screenshots, this cat is a bad example. Sorry, Shoo !

Next a screenshot of the post embark cheat-mode indicated by the "Knapped points:" counter. Since dwarves are much easier to assess here than in the embark preparation screens, this feature allows skill points to be redistributed, but keeps track to make sure extra are not added.
In this screenshot units are also sorted by "medic" which ranks most highly generous and non-sadistic personalities. The top dwarf looks like a decent leader/manager type so...

Here it is on attributes tab again and redistributing the 'knapped points' to make Glovedikes a better leader.

This is the help screen showing the meaning of the attribute grids header.

There are some more tips in the help screen but it currently needs to zoom out to show everything.
Cavern keeper is not difficult to navigate. Control of sorting is simpler than manipulator, yet the sorting options are much improved. The Tab key changes what is displayed beside the labor grid (professions, squads, current activities, notices or body attributes). A couple of mode keys cycle through color and theme tweaking options, configuration and focus is persistent. All the control keys are displayed in the footer, the only controls which are not obvious are for the cheat options.
