Looks like I'm late to the party, but I will second the idea of pull out shelves for lower cupboards. I also love big drawers instead of some lower cupboards.
A very simple thing that I got for an apartment that I used to live in was a hanging pot rack. I put all my most used pots there and it was a pleasure to get them and use them. They didn't get dirty hanging because they were always in use. I loved it so much that I brought that idea into the house I now live in.
When I was designing the kitchen, The peninsula was going to be a few inches shorter than the length of it on the back cupboard side, which I was thrilled about. Between the extra freezer (topped with a butcher block as a great cutting board) and the stove, I had about three inches to play with. This is the perfect spot to tuck my step stool. Being I've "shrunk" to 4'11", I use that stool on a daily basis!
I also have replaced a lot of appliances with an air fryer. I no longer need a toaster, a toaster oven and mostly, I don't really use my large oven. I've baked an entire chicken, many pies and other decent sized pans of food in the air fryer.
I keep a stool in the kitchen, which I pull out when I'm kneading bread. The height is much more suited to that activity than my counter top. I use the largest size stainless steel bowl to both mix up the dough and then knead it in. It spins nicely on the top of the stool and I can push down on the dough rather than having to keep my arms elevated. Much more comfortable!
I also use the stool when I cleaning fruits and vegetables. I open the cupboards below the sink, and that way, I can pull up close to the task at hand. The "floor" of the cupboards act as a footrest and my knees can fit under and into the cupboards. Strawberries can take more than an hour of prep, so it's nice to settle in and be comfortable.
As a friend always says, I'm a master stasher! Beside the refrigerator and up against a wall, there is some space. In the late fall, when it's time to take out the screens, this is where I tuck them. They are out of sight, but easily accessible with the change of seasons. On one of the first warm days of spring, I can easily take them right outside and dry brush them to get the dust and cobwebs off. If needed, I can wash them and then hose them down and leave them to dry.
Here's another tip that I learned the hard way. I discovered that my sink was leaking after having it repaired less than two years ago by a professional plumber (who's business rate was $175 and hour...standard in these parts; supply and demand, I guess.) Anyway, the new plumber I called asked if I canned. "Yes," I replied. He told me that by pouring a huge pot of near boiling water down the sink, it had warped the PVC piping they all now use. I showed it to me. Sure enough...He said that I could let it sit and cool for a bit longer or just run cold water as I'm pouring out the canning water. Hope this helps someone!
