A while back there was some talk about coin control. Staking leads to smaller and smaller coin "chunks" over time. If you activate coin control in the options of the KTK wallet, you can see those chunks in the "send" tab. If you have a lot of chunks (500-1000+) this can lead to performance decrease.
With coin control, you can select some of the small chunks and send them to yourself, resulting in one big chunk. Note, however, that you have to pay the transaction fee for this, and also the big chunk starts with a coin age of zero. Nevertheless, after some weeks of staking, I would recommend consolidating the tiny chunks into bigger ones.
Also: #3698, bye bye THC
EDIT: A lot of small chunks also lead to long loading times when sending coins, as hundreds, or even thousands of coin hashes have to be combined into the transaction which takes time (I'm sure some technically minded person can explain that better but the gist should be correct).
this should be put to a guide. srsly plz!
