increasing the size of the file manager

another thing that would be helpful at all when placed pictures of the products >> increasing the size of the file manager by vertical size and/or horizontal size + option to remember the last directory. ideal to get all big and small shops with lots of pictures of the products. pictures of the screen does not get misunderstandings. I tried to do it myself and css file and *. php file failed. would be great to be done in the next version

This is a feature of Admin Enhancement Suite. Default image manager size is 800 x 400 which only lets you see 8 images at a time. With Admin Enhancement Suite you can set it to 900 x 500 (15 images on screen at once), 1000 x 600 (18 images), or 1200 x 800 (28 images).

I believe there are also a couple free stand-alone mods which change the image manager size which you might be able to find with a search.
