Hi Gav,
As you indicated some of the things are already there. In fact, if you attach an Env catalog some other thing become available. I recently opend and Env file in TFP and it opened Ok, rendered OK and enabled other dialog boxes that gave additional functionality. Obviously some things in TFP are just "turned off".
Some of the 'things you want fixed' can be fixed yourself in the Settings - it does not need IMSI to do anything. You do not have to reset things for each drawing if you choose the right startup template. For instance, mine always shows my chosen printer and is always set to Perth at my preferred time and with all my preferred render settings. All you have to do is set things as you want and save this as a startup template, then select that file at Settings/Program Settings/General (otherwise you will be back in Canada with the default one).
Although I have not checked it I think you will find that import will import as mm is the original was made in mm.
I agree Duplicate is different to Cut and Paste but I must admit I have become completely used to Duplicate and don't even think twice about it now.
The keyboard Delete key works well as an eraser - or you can right click and select Delete.
I am not sure what you mean by "basic keyboard config". Keyboard keystrokes are available for most things, if that is what you mean. Alt I and W will Insert Walls for example the underlined character in the menu being the key character in usual Windows fashion. Ctrl P prints, Ctrl S saves, Ctrl Z undoes and Ctrl Y redoes (C and V don't copy/paste though - that would be a nice addition!).
