Hello,
A general question.
I am starting to gain an interest in programming the Atiny85.
And I wonder how much of the debugging/development work I might be able to do in another more development friendly device - such as a Nano etc.
Are there any words of wisdom for someone interested in pursuing that process?
Sincere thanks!

I would start by loading ATTinyCore into your IDE to support the '85 and understand the features you have chosen to work with.
Much as I love the '85 it's getting old and isn't the easiest thing in the world if you've only used Arduinos. In particular, the lack of a serial port makes debugging quite tricky 
You might take a look at the newer ATTiny devices which are better & cheaper.
I confess a minor commercial interest here!
I use & sell a ATTiny1614 board. attiny
I prefer the ATTiny84 to the 85 - a few more available pins and an 8bit as well as a 16bit timer (unless you need the high speed 8bit timer of the 85). I use the QFN package (small and cheap).
Also, I just hook an I2C LCD screen to it for debugging. Works fine for the 85 as well if you can spare the two I2C pins.
And yes, the ATTinyCore is a must.

Wonderful answers!!
Thank you all very much!
I'll check out all of it
My sincere thanks!
Love the toys!! :-]
Spend some time reading over the attiny core GitHub home page that was linked. Spence has each supported chip explained in great detail along with the pinout images. I find those images very useful for figuring out how I’m going implement a particular idea. Sometimes it’s more of a “can I do this” check with the i/o configuration for each variant. It is a very well documented, high performance core. Be sure to check out his boards on Tindie
Spence Konde certainly seems to be the man for all things tiny :o
Check out his megaTinyCore: GitHub - SpenceKonde/megaTinyCore: Arduino core for the tinyAVR 0/1/2-series - this is any ATtiny with 2, 4, 6, or 7 in the 1's place, 0, 1, or 2 in the tens, and the flash size in the remaining digits. LIBRARY AUTHORS - Does your library have issues with this core? Please touch base w/me so we can ensure a solution that works on all parts and won't be broken by future changes This might persuade people to look beyond the 84/85 and look at the recent devices which are seriously good!
I prematurely posted a link to my own ATTiny1614 offering showing a half finished page full of errors, especially the pricing I've corrected it now. The actual price of my PCBs is 2 for £4! Not £20 each or whatever it said
