After ES File Explorer turned into spamware I've started using Total Commander v2.91.
It has a steep learning curve, but I can see it is influenced by the very old MSDOS file commander. I appreciate the fact it can access my PC via the SMB shares.
I'm just learning how to make the most out of TC by adding custom/frequently-used buttons to the Button Bar.
...Which has revealed a visual bug...
○ The icons for "Cut" (to clipboard) and "Copy" are too similar. The only visual difference is that one has a slight red tint piece of paper while the other has a slightly green-tint.
○ If the "Use new icons" is selected then the toolbar & button-bar icons all appear as grey - so the Cut and Copy icons are now identical!

○ If I unselected the the "Use new icons" and use the old icons, then at least I am able to see the color tint, but they are still too similar and for color-blind people I imagine it would still be impossible to tell them apart.
I know I could seleft a custom .PNG image for button-bar icons, but making this change would help everyone who wants to use Cut/Copy buttons.
Best wishes & stay safe!
