For me it is always difficult to see the groups in the permission groups, I would prefer the user part would have one color, the group part another... identifying if there is a r or w is not the problem. There should maybe be also between the groups a space, just to make the output more readable. Otherwise I would like to not see the file creation/change date at all, since most times it adds no valuable information. To get more verbose output - with date info, there could be something like exa -ll (make the output more verbose if there are more -l args present). Just some ideas, maybe you like some of them :)
