Me too... I just created an account as well.
I usually use the free version from time to time. It does most of the job. There are many things that I like on ccleaner but somethings I don't. One of the things I really don't like is that most of developers don't think about every person and their disabilities like poor vision or people that spend most of the day on dark environments like mentioned above. Since Windows Vista era, the OS and programs usually display few text over the white background. We are always being exposed to white light.
In my case, I have poor vision and most of things are set to dark mode and when I can't do it, I have to use magnifier and use ALTgr+I (CTRL+ALT+I) to invert colors on the screen. White becomes dark, dark becomes white, etc... and things are more readable.With ccleaner is no exception. I have to invert colors to move myself inside of ccleaner.
The question is: WHY PIRIFORM DEVELOPERS CAN'T ADD A DARK THEME TO CCLEANER AND OTHER PRODUCTS? It was easy adding unneeded colored buttons (that also annoy me.... yack... at that blue themed buttons).
Pretty please!!! ADD A PRETTY DARK THEME (WHITE ON BLACK, NOT GREY ON BLACK) to the setup of ccleaner, ccleaner, recuva, defraggler... etc!
