a few bugs and modifications

Hi there,
I like the theme and by far it is one of the better ones i used. however I do have some issues:

1- how do I remove the "latest offers counter and the box itself".
i want to expand the slider next to it by adding one more product and adding some extra tabs to it. please see the image of what i mean.

2- i would like to remove the image zoom effect and remove the hover buttons and have permanent buttons below the product instead.

3- on the search bar select box not all the main categories are showing up. and when the drop-down box is clicked it remains down forever even if you scrolled all the way down a page.

4- item descriptions on the search view look too dissimilar to each other. i mean why not make them all standardized like:
a- item name (limited to a certain number of characters and then followed by "…." if too long a name)
b- item price or crossed lined old price
c- item actual price or discounted one if applicable
d- rating
e- product condition (new vs used)

5- i would like to report a few bugs that are kind of annoying.
a- one can only click and type on one half of the search bar only for some reason!
b- there are some responsiveness issues, like if the page was half screen size, the items on the widgets don't show the correct price, only the zeros after the point.
c- one of the most annoying things is the image cropping. half of the product images are cropped instead of re-sized when the user adds an image of the wrong size. this gives a very unprofessional and unattractive look.

would really appreciate any help on those aforementioned points please.
