Hello,
I'd like to suggest some small ideas

1) Calling out Names - There was a feature in USKO to call out names in chat of a person. You click on the person and then you press F11 and that person name will be on chat. This is really useful feature for PK.
Priest can debuff someone and press F11 to tell us who to aim instead of typing in those crucial moments. Or anyone in party just call out the enemy name so that we all can focus one instead of randomly scattering away.
2) Walking while Alt+Tab - I know its not a big thing but as many people might know when you press E you keep on walking straight. So I used to press E and then Alt+Tab to do some other work and Alt+Tab back in game to see that I have reached my desire location. But at the moment when I Alt+Tab I stop moving right there only..
3) In-Game Clock - Small in game clock would be really helpful for people. We already have a time-table for events. A clock according to the server would help alot of people to know when is which event going to happen. I mostly see it from Forum-Clock but still it could help!

4) Free Restat/Reskill Option in Panel - A free restat or reskill option in panel would be really helpful seeing alot of people go through the 120 unset bug. You can provide 1 Free restat and reskill per week. This way many people would also love to change their skills and try other things without worrying about spending nearly 1gb.
5) Exact Description of Skill - Many last 85 lvl skill are really bad in description. ( And the warrior attacks the earth summoning a quake, Last blow etc etc. )
Letting us know how much %% damage they do or what they are supposed to do would be better.
I have some more but I guess I'll just put them out slowly slowly

Thanks in advance!
Birdie
