Thank you so much! Especially for the NVIDIA advice and it does seem like KDE is the best option. I've used some KDE stuff before and liked it.
However I disagree on the the shell one-liner for renaming. I often do complex multi-step operations. Incrementing and decrementing for example one set of numbers in naming while not touching another, changing capitalization, removing x number of characters at the start or end, and so on. The time saved by a GUI compared to remembering and typing all this out (and dealing with my errors in syntax) each time is easily worth some money to me. I already have a number of scripts I use for managing my media and working with mkvtoolnix for instance but looking at how I do renaming, the number of scripts would be endless and editing them each time would be more trouble than it's worth. I'll find something though, this I'm willing to spend time on to save time haha.
Workflow, ugh. Well of course on some level I'd like to keep what parts of it I can. Do you like suddenly changing long-learned routines? If you buy a new phone are you DELIGHTED to see the settings sections have been all scrambled from what you're used to? I understand things will be different. I'm okay with this. But if I can find tools that let me keep parts of my workflow while working great, why wouldn't I?
I'm trying to replicate tool-sets I use to do things.
Thank you for your suggestions. I appreciate it.
I'm not asking for a control-scheme that works identically, just functional equivalence where possible and alternatives to achieve my desired functionalities where not possible.
I'm asking for tools to help me do the things I use my computer for. I need something that can do powerful searching in text files which is why I mention that. I mentioned "DESIRED" not required features. Powerful text editors are a very personal thing, lots of people have preferences and reasons for them which is why I ask while informing others what I need above and beyond basic inputting of text.
I'm a shopper shopping for a new OS. I'm listing things I'd like to those in the know and one person here has taken it upon themselves to act like I'm some arrogant entitled spoiled nepo baby demanding to be supplied with an exact copy of what I have when I'm merely asking if comparable things exist and what are they or how would I accomplish this. (My goodness, my original question list was twice this length but I managed to find a lot of answers myself however thought I'd avail myself of Linux's famously social and positive community)
Fortunately from the many people here who've commented I've decided I think I have a basis for a start. So thank you nearly everyone.
