Locating a wrong formula among others is extremely difficult (may have to compile all formulas one by one.) so there is no good solution yet. > In conclusion, the existiing solution and your proposal convey appear > equivalent information, but yours introduces different (note, not > 'better) behaviour for a 'just-edited' inset. If 'not-turning-to-image' is a definite and alarming sign of wrong formula, you are right. However, this is not the case. 1. Correct formula might not be previewed. One simplest example I can think of is: enter a \alpha, wait for preview, copy and paste this alpha. The new one will NOT be previewed unless you enter and leave it. 2. The current indication of wrong formula is 'nothing happens to the formula afterwards'. This is psychologically hard to notice especially when lyx math box is a *normal* status of a formula. 3. previews need a while to appear, people will not wait and see the result. (Even when they wait, most likely: nothing happened yet... lyx is still compiling? instant-preview does not work? Just another not-shown?) > Forgive me, but I do not see why this is any improvement at all. I consider this patch as a minor improvement with minimal cost but of course you guys are the judges. :-) -- Bo Peng
