Possible improvements for search grid feature

• Need to destroy every session?
• Explore multi processing for button creation
• Reshuffle assets accordingly upon window resize, probably can store buttons in a list and just call .grid. Not sure how to deal with button image resize at the moment though
• Make full use of real estate, after finding each row's width, resize width to same length as all rows and scale resize height accordingly
