a. timestamp: reduce to date only (remove weekday & time, which can be viewed in "details")
b. short url: stack in same column as original url (provides better visual comparison of url lengths, also it's duplicate data in different format, so adjacent column is meaningless)
c. original url: excellent
d. thumbnail: remove altogether (it can be viewed in "details", conserve bandwidth & increase number of rows visible for comparison)
e. ad: great
f. hits: split into columns (talk about increasing row visibility! with column space gained by removing original url & thumbnail columns, turn these 12(!) rows per link into 2 columns in 2 rows by changing "hits" header to "link<br>clicks" & "ad<br>clicks" then printing data as valid: #<br>total: #)
g. Please make every column sortable (on main page as well as "details" page), the link stats will be much more valuable when we can sort by total link clicks, total ad clicks, original url, referrer, etc.
