I am now revisiting the LTS tool for a little potboiler of mine and see that the latest ver (from LTS IV) is now jumped to LTS 7. I am having to relearn here so its a bit of a slog. FWIW its an indispensable tool and forces design thinking rather than the dirty suck-it-and-see approach by rank amateurs.
I hope Im in the right place for my discussion here - pls mods re-direct as necessary as there's no obvious forum category here.
enough intro
There are many little quirks and inherent bugs? to learn workarounds which LTS users are fully aware.
One that completely floored me was that resistor models have an inherent POLARITY. Fell off my stool back then. In a word it makes a difference which way round you insert the resistor to your circuit - just like a battery. GO FIGURE

Sadly there is no obvious tag to show polarity on the schematic or any dropdown info (like +/-). This can so easily catch you out especially if its not obvious which polarity you have with applied voltage - like a wheatstone bridge type cct)
I have a simple solution, but its so obvious that the 10^6 users over 20 years must have thought of it. It involve putting a simple dot on the symbol to show positive end. I can post the trivial .asc file here to help anyone else but I fear that there must be a fatal flaw to such a simple method.
Would any experiences users here please deflate my hypothesis - its bothering me.
