There needs to be a way to definitively know when clan members were on last

I know this is a subject the developers aren't considering at this time and this thread will probably be removed, but please hear me out. No clan that wants to be successful wants inactive members, but with the way things are now kicking someone for inactivity is a judgement call. Right now in my clan I have to go by how often someone uses the chat and how full their collectors and mines are, but the problem with that is the person might not be much of a talker or I looked at their base at the wrong time. With a simple number next to every persons name in their profile or in the clan menu I and every other member can clearly see how many hours or days it has been since each person was on. With that I could have a clearly defined rule in the clan that states if you aren't on for let's say 3 days for example you will be kicked and if it says 3 or more days was the last time someone was on last when I kick them there can't be any dispute. That person clearly was not on for 3 days or 4 days or whatever. I play another mobile game that has this feature in its teams and it works great. The team I'm in has a 7 day rule and if they aren't on for that long they are removed from the team. Again I know this isn't a subject that is being considered but I needed to express my concerns and opinions. Please think about this Supercell. I'm sure I'm not the only person who would really appreciate a feature like this. Thank you.
