I use "Shopware" for a merchandise shop for example. There is an option to clear all caches at once or individual caches for themselves.
Thumbnails, sitemap, user caches, permissions for example could be cleared in one step. The reason is just that I will do it anyway, but now I have to do it manually one after each other. And I want to clear them altogether, for example in a developing phase where I do it more often to be sure that all changes are applied.
With the current process it is hard to keep track sometimes, especially if you do it over multiple add-ons. The page jumps to the specific add-on cache page with some add-ons and then you have to go back again. I want to just hit one button once and then all caches get cleared automatically while I go and get a coffee. To reduce server load, there could be presets or blocks as I mentioned in the post before.
I hope this is somehow more understandable. I just think if a shortcut makes sense, then with cache clearing.
