Components Anywhere doesn't do much, really. Just easily let's me place components anywhere, just as it says in the title. That's one thing I like about NoNumbers' extensions: no frills, easy to use, reliable. Plus great service.
In the backend there are some options for styling of the tooltips that don't seem to have an effect. Many options are marked "beta". But as far as I tested the extension, it works well and I found it easy to use.
I'm really grateful the author wrote this. Excellent.
I had one issue: a component appeared twice on a page.
Here comes the author's support: Problem reported Friday night, fixed update delivered Saturday early morning ...
Only issue I had was that the thumbnail spans had a greater size than the thumbnails. There are constant numbers of pixels added in ppgallery.php, near line 363. Why these are added is beyond me ... I simply deleted those constants, now everything's fine. Thank you!
