Hi, I believe we need some functions:
1- alias for categories & fields.
because we don't have it now. I used sh404sef. but there is a big problem. all the links has to be changed manually. Imagine I have a category called "املاک" (UTF-8 Persian lang) and sub cat "آپارتمان" then an ad has been created "فروشی".
The link has to be some thing like this:
/فروشی/آپارتمان/املاک.html but it shows like /املاک/آپارتمان/فروشی.html
the problem is Persian RTL lang but there are lots of UTF languages. then if there is an alias, we can have English alias instead and then we don't need to change it on sh404sef.
2- promotion ads (paid) to show in the front page.
I asked for it & I got answer from Joomprode that I can use paidsystem_feat module. But lets say if we want to have all the ads be free to create. but who wants to show their ads in the front page has to pay.
3. Star promotion (paid)
look at this site
www.istgah.com they have promotion ads with 7 stars. they charge people for every star. it means If you pay for one star your ads will be on the last in the list but if you pay 7 stars then you will be on the top list. :)
4- New ads (Submission) show
now we can set our elements & arrange them in list view & details view. It would be nice to have the same functionality for new ads page.
5- Field Parameters for elements
For having opportunity to change some parameters such as width and ...
PS. It would be nice if we have that for all pages separately then for example we can change the width of an element in submission page but it doesn't effect on the list view because list view has also its own parameters which can be copied of elements or change it for its own.
6- Default value for elements.
when we create an element it would be good idea to be able to select default value for some of them.
7- price ajax function
if you go to this link
www.edbpriser.dk/computer/barebone-pc.aspx look at the "pris" (price in Danish language) it will automatically select min-max for all the ads and then have a slider for selecting min-max. those numbers will change if you go to another category.
PS. that function can work best on all min-max elements.
8- Predefined country, regions, cities.
Have ready element for continents, countries, regions & cities as default then every advertiser doesn't has to add it manually.
PS. I have created full info for Iran. If I find time I would do the same for all the countries & then you can have a copy to distribute it to others.
9- Categorize elements.
I have created lots of conditional elements. Imagine how I can find an element between that many. I know I can search for it but how if you don't remember what you called it?

In the other hand, if it is categories it will be easier to check what, where, how, how many elements.
10- Textarea editor
Some thing like Tinymce for text area & option for enable & disable & include/exclude functions.
At the last please forgive me if there are some of these functions in your program & I didn't know.
Cheers
