There seems no way inside CataBlog to see the term_id of a category. This is important when excluding categories from being visualized with a Cloud widget, for example (btw, nktagcloud works great with CataBlog). Now one needs to go to the DB to look for this.
It is obvious the developer has put a lot of thinking of keeping the UI clean and easy to use and kudos for that! In that aim, maybe a suitable place to put such information is right next to the "View" dropdown in CataBlog Library. Namely:
catablog\templates\admin-library.php li ~55
<input type="submit" value="Filter" id="catablog-submit-filter" class="button-secondary" /> <?php if ( !empty($selected_term->term_id) ): //[alx359] Added. Visualize term_id ?> <small>[term_id=<?php echo $selected_term->term_id; ?>]</small> <?php endif ?>
