There are some issues with the current version of the UW as of today (2015-12-10).
* Selecting another language does not work, advance typing is not left bound (typing eng should select english, but it selects altenglish at the moment, as there is no way to select the second / third / … value in the select box. The only choice as for now is to scroll down the complete list and find the additional language (usability!)
* Selecting categories should allow to navigate the category tree the same way HotCat does. (here category names are left bound!)
** this should include the possibility to change already selected categories (like with HotCat).
* backspacing characters should stop at the category border. It looks as if a category entry is treated just the same as a single character. One backspace too many and the previous category will also be deleted. backspace needs at least to pause considerably.
* Where is the enlarged preview of the thumbs? (by clicking on the thumbs)
