Baby gates have been my best option -- I simply make sure the pup is in the SAME ROOM with me all the time. If you know your attention is going to be focused 100% elsewhere that's the time to pop her in her crate with something to chew on.
With Tink those 'flavored' (they are marked "Durable" on the package) Nylabones work well. I had to train it a bit but I can usually 'trade' her for one of those. Not all dogs like them but she likes those HARD flavored ones -- apparently they are a good chew for her.
Keeping a variety of marrow bones in the freezer to trade out for whatever she's chewing inappropriately will help. But honestly it's the same sort of 'mom-radar' you have with your kids that you develop with the dog -- if it's quiet THERE IS TRUBBLE.
If all else fails or if Tink repeatedly gets in trouble over and over when she's RIGHT near me, then I resort to putting a leash on her IN THE HOUSE and tying it to whatever is near me (that is far from the chosen temptation).
She hates it -- but it's simply keeps her out of trouble. I then give her something ok to chew on. There are times even NOW when she is just adamant she's going to get in trubble and I'm just as determined she isn't. And an hour spent "on the DREADED BLUE THING" can sometimes simply remind her she has to stay withint acceptable norms.
It's not horrible, it's not even crating her "away" from everyone else. She has something appropriate to keep her busy -- it's just preventing disaster.
Remember, Kira is hugely teething -- she's beginning to get secondary teeth that are DEEP and those hurt like the dickens when they are trying to break thru -- so honestly, try to find something for her to chew that may mimic that gnawing she's trying to do now. The windowsill "works" to do whatever she's trying to accomplish -- she can probably bear down on IT (which is tough to do with something you're just "holding" in your paws).
Another thing that can work really well that works great in a crate is a HUGE HUGE HUGE block of ice. Like spray with Pam and freeze a Quart Glad container with just water (or add just a minute amount of beef juice or apple juice to it) and freeze it SOLID. Then it should drop easily into a dog dish that you can put in her crate. (Let it soften in the fridge just a bit -- sometimes I do this stuff in advance so I have some "freezing" and one "waiting" in the fridge) and when she's adamant she's going to chew you can give her something that will help anesthetize the pain a bit.
And exercise -- don't forget that a Kong can be GREAT fun used as a 'ball' rather than just something to eat from. Because of it's shape it bounces abnormally -- and it can be a great toy for a kid to throw for her outside -- it will keep her zigging and zagging in all sorts of directions.
Sometimes the word 'supervise' has to be modified so you can "multi-task". No one has time to just sit and stare at the dog -- but using tricks like leashing the dog to a table leg (while you are standing In the kitchen doing something else) or behind you while you are working at the computer-- it's not as restrictive as 'crating' but it is also keeping her in arm's reach while you're busy with other work. And where you won't hear her in *another room* chewing on a windowsill you will train yourself to hear the different sound of her chewing on furniture as opposed to chewing on a bone or Nylabone.
I will add -- the soft plastic chew toys (like the "Keys" and the softer more flexible Nylabone stuff that is also apparently "flavored" -- Tink is thru that in literally under 2 minutes. I have to take it away from her.
BUT BUT BUT -- there were times when she was in the throes of 6-9 months intensive chewing that I gave it to her and would snag it and "cut off" the chewed up parts of it every few minutes. Because for SOME reason that flexible chew was what she ****needed**** badly at times. Then later I was able to trade up to the "Durable" chews.
THESE were her favorites (and I've gotten them from here too)

These are the ones I get for her now (and they DO last but are attractive)

The ones marked "Durable" can be hard to find. If you go to Dog.com's whole page of Nylabone stuff -- it's specifically the ones marked "Durable Chicken" that I can walk away from her and not worry about her chewing bits off. Those keys? She LOVES them but dang -- I have to be right next to her with scissors (big honking kitchen shears) to cut off pieces she's chewed so I can throw them away so she doesn't ingest them. BUT I can't emphasize enough that when she was the age Kira is Hokey Smokes Bullwinkle SHE NEEDED TO CHEW.
Now she'll chew a fleece toy and not destroy it (Billy ... could you PLEASE learn that???) but a plastic chewey toy? man, she's Destructo Pug -- but it seems she has really **needed** that deep teething at times to keep her from chewing on my furniture!!
And btw -- the only thing I found that she hated enough to discourage her from damaging wood furniture and pieces of my house was White Flower Oil or Peppermint essential oil (and I think the SMELL of it was just too pungent for her to tolerate chewing). Both of those are massage oils -- but dang, it worked to get her off the armrest of the futon without poisoning her!!
