Hi,
Have you considdered changing the Add Listing form to be a multistep process?
The form easily get very very long with alot of information that the user needs to enter.
It would be a really nice feature if i could break it up in like 3 steps, with basic information on first page, location information on next and contact information or similar. It would enhance user experience quite alot, and even more if the form saves the data so they could turn back later (maybe thats already implemented?)
On listing details, the slider could easily be changed with some css, but have you also considdered making the images smaller in generel? They are really huge and take up most of the screen on a 15 inch laptop. See attachment.
Regards
Brian
