Copying a block from one tab to the other will be a very convenient feature. The need to export/import is usable but a little bit heavy.
Any technical difficulties?
Not a all!
Pas du tout du tout.
On my side: integrating new 'profile' and 'search' functions (gloire à Toms and Moudubou).
No time allocated to take care of that!
Orgams doesn't support (yet) the LIMIT directive.
Poor man's solution:
dev = 1
texture = &1c00
[...] ; your questionable code
; End of source
IF dev ; When dev=0, source size won't be artificially changed.
SKIP texture - $ ; Mimick "LIMIT texture"
If $ is greater than 'texture', the argument is negative, hence assemblage error, which is what we want (to be warned about the overlap).
If $ is less than 'texture', no problemo.
If $ is equal to 'texture', the argument is 0, which is fine (last opcode emitted at texture-1). SKIP 0 doesn't do anything, as expected.
About the incoming #10d TODO concerning SAVE directive: will it allow to save any area of the memory?
Yes, since you can assemble at any area of the memory (modulo bug #e2).
Do you have a particular scenario in mind?
Note: the general rule is to present what to want to achieve (alongside with motivations is even better). It lays the ground for superior discussion and solutions.
