  • A way to copy/move to several categories at once. One way to do that would be to require the user (perhaps only if they've set it so) to click "save" before Cat-a-lot actually does anything – the user could then have clicked several "Copy" and "Move" buttons before and Cat-a-lot would do all these operations. darkweasel94 12:02, 13 October 2013 (UTC)

It applies to all categories that are added through templates, because these aren't in the wikicode, so Cat-a-lot can't really detect them. If you click "Copy" instead of "Move" in a "Media needing categories" category, it will do what you want, as it always removes {{Uncategorized}} if you add categories through it. darkweasel94 19:22, 10 June 2014 (UTC)

    Categorization is now done async for a while. This means after you request the categorization, the database still does not know it (for a short moment). It is considerably fast, but it takes, in my feeling, much more time than cat-a-lot takes. May this explain the observed behaviour for you? --Herzi Pinki (talk) 14:46, 10 August 2016 (UTC)
    Usually, the problem is caused by invisible characters (marks) in the category link (the problem is mentioned above at least twice). Some tools and functions ignore them (i.e. the pages are displayed in the linked parent category), but other tools are blocked because they are not able to ignore such characters and recognize the linked category. There are not unified standards for interpretation of categorization links. In case of repeated attempt with identic page, delay of displaying of page content can be also a cause (the category page displays a content which was moved recently). --ŠJů (talk) 16:24, 21 August 2016 (UTC)
  • My most common use of Cat-a-lot is when moving categories. For example, a CFD resulted in the entire Category:Gothic revival architecture tree being moved to Category:Gothic Revival architecture (capital "Revival"). This being a common architectural style throughout the Western world, there are tons of categories to move, and each time I move a category, I then use Cat-a-lot to move the contents to the new title. Whenever I move a category that's in use, the old title gets put into Category:Non-empty category redirects, and so whenever I'm moving the contents to the new title, there's always a chance that I'll misclick and put the contents into this maintenance category. Therefore, my suggestion: instead of automatically giving the option to move contents to a parent or child category that's tagged with , have Cat-a-lot hide them and notify the user that hidden categories can also be used if the user specifically selects that option, so that two or three clicks, not one, are required for moving items into a hidden category.

  • Bug: if you move a category page to a different name and then try to move its contents using Cat-a-lot, the gadget stucks. For example, I want to move Category:A to Category:A1. If firstly I move (using the regular move page ability) Category:A to Category:A1, then go to the redirect page in Category:A and try to move all its contents to Category:A1, the tool just stucks. If I try to move Category:A1 back to Category:A (now Category:A1 redirects to Category:A) and tries to move Category:A contents to Category:A1, the tool doesn't stuck at first, but if I search "A1", the search stucks again.

  • I do a lot of categorization of unidentified images. I go to, for example, https://commons.wikimedia.org/w/index.php?title=Category:Media_needing_categories_as_of_4_December_2016. I click on Cat-a-lot and enter a possibly appropriate category name, for example, "Association football clubs of the United Kingdom". Cat-a-lot returns "Category redirects" above it. If I copy the image to "Association football clubs of the United Kingdom," the image is now on the redirect page. Why doesn't Cat-a-lot, recognizing this is a redirect situation, automatically generate the correct category page, so that I can now follow its tree, and I don't have to leave Cat-a-lot? To get the name of the page that "Association football clubs of the United Kingdom" redirects to, I have been opening a new tab and pasting the name in, and following the redirect, which is unnecessary work.

  • Hi, the handling of {{Uncategorized}} seems to have changed. When using cat-a-lot on a category (and presumingly on a gallery (I did not test this)) to add categories and if your preferences have Remove {{Uncategorized}} checked, {{Uncategorized}} is not removed any more (e.g. categories underneath Category:Photos from Panoramio needing categories by ID). Maybe this is by design, but rather impractical. Please restore the old behavior, in the worst case the file will be tagged as {{Uncategorized}} by some bot again. best --Herzi Pinki (talk) 09:12, 25 November 2017 (UTC)

Don't see a bug in HotCat, it's a feature. You add a cat and {{Uncategorized}} is removed. This should be the case even when the target category Category:Xxxxx does not exist. I usually first add the category to files and create it afterwards. I use the Xxxxx temporarily to just get rid of the marker (there is no way with Cat-a-lot to just remove the marker).
