puzzles - usability problems

Storm is wonderful BUT there are several glitches:
a. It reacts to fast: I do not see the moves played, I do not see the result of the puzzle. Chess.com time is much more convenient to me. It is really unbearable for me as it is. Can you at least parameterized the delayed time?
The feature of the failed & slow puzzles is VERY important. However,
b. The last puzzle is regarded as failed while in realty the user did not have the time to finish it. Maybe leave the last puzzle on the screen so that the user can continue solving it. (without counting it as success/failure)
c. There should be a smooth way to go through all the failed/slow ones. Nowadays, after click on one of the puzzles, getting it, solving it and clicking the OK button the user gets a new puzzle which is rated(!) while it expect to get the next failed/slow one. (not to mention the discontent from decreasing your puzzle rating without you explicitly selected to be in a
d. In order to go through the list the user have to remove the tab, find in the displayed puzzles which puzzle he/she solved and click on the next one.
e. Generally speaking, the main feature I miss (I know this is stupid) is simply solving problems which get harder/easier according to my success without gaining/losing my puzzle score. Imagine that I’m tired and want to enjoy solving probes but not trivial ones. I do not enjoy losing 100-200 score point at 15 minutes nor do I want to work hard on puzzles that are at the limit of my abilities. So just let me solve probles without keeping the rating. For me this feature is the most missing feature in this wonderful site.
thank you!

a) Well, puzzle storm is supposed to be fast. It's timed after all. Also, if you fail a puzzle, it will play a noticeable sound and the whole right side will flash red. It should be pretty obvious.

b) Does it really make a difference? It's not like failed puzzles are counted for anything.

c/d) I agree on this one. But you can just open all failed puzzles in a new tab by clicking them with your mouse wheel or holding Ctrl and then go through them one by one, closing the tab after you're done with each.

e) You can select a lower difficulty when doing puzzles. Although I guess you lose much more points when you fail a puzzle then. I guess a casual puzzle mode might not be a bad idea.

"simply solving problems which get harder/easier according to my success without gaining/losing my puzzle score"

that's exactly the purpose of your puzzle rating: to give you harder/easier puzzles according to your success.

So... basically what you want is to hide your rating, I guess?

WHAT

where probems?

@ps30
to your point e.:
maybe puzzle streak is what you want to try: you can quickly jump through the trivial ones and get really good ones soon. Comes with no time pressure but with the tingle that you do not know, when the trivial ones turn serious

Busted @ps30

Puzzle rating is what adjusts which puzzles you get. It's designed so that you will successfully solve approximately 50% of the puzzles.

Perhaps you want some kind of rating system that is adjusted so you solve a higher percentage of puzzles?

That already exists, it's the difficulty selector. Set it to easy.

@ps30 If you don't want lichess for this, you can use chesscup.org.
