Equation Editor 2.8 breaks up

Thanks for your further feedback.

Ok. Firing through your list above, one is a bugs, the rest are design changes.

1. The fraction function, originally was written as but now its shown as . The reason for this change is we've been carrying out some usability tests on people completely new to the system (yes, surprising we did test this aspect before going live :) ). What we did was wrote down a dozen different equations and asked them to write these using the editor and in doing so, we noticed how they worked. For those familiar with maths, the original symbols worked fine, in fact they preferred , however those not strong in maths couldn't immediately find the fraction button. However when shown , everyone recognized this for a fraction. Thus to keep all sides happy, we show in the yellow popup the equation in the original form of a/b, but show by default . We've repeated this for other symbols, like integral etc. the hardest was with subscripts like . Interestingly if you following Microsofts lead on things, then they typically write subscripts as , but in the equation editor (by MathType), they use squares everywhere. What does anyone else prefer? Of those that have written to me, they prefer the original, but is that just because they're used to that now?
2. Dropdowns for Styles, Foreign, Symbols etc are now all represented by graphical panels which show exactly what you get. For Foreign and Symbols in particular this is much more logical and as I hope you'll appreciate the selection is much much greater. The ordering (and indeed the breakdown) of symbols within each panel is I admit a subject of much debate. For the most part we have adopted the grouping laid down within various LaTeX manuals, i.e. 'Foreign', 'Binary', 'Styles', 'Greek letters' etc.
3. The 'Render Equation' text should be right now; I forgot to copy over a language file.
4. Would rather solder on with 2.85, rather than drop back to 2.6. I appreciate your annoyance and after this version this won't happen again; however many of the bugs you've raised are actually feature changes (therefore technically not bugs) or they are bugs in 2.6 also.

Coming back to the drop down panels. The major difference between 2.6 and 2.8, is that these panels are now automatically generated on the server. There are a collection of xml files that define all the buttons within each panel, for example, uppercase greek letters panel is defined by:

<panel>
<col>
<eq><latex>\Gamma</latex></eq>
<eq><latex>\Theta</latex></eq>
<eq><latex>\Xi</latex></eq>
<eq><latex>\Sigma</latex></eq>
<eq><latex>\Phi</latex></eq>
<eq><latex>\Omega</latex></eq>
</col>
<col>
<eq><latex>\Delta</latex></eq>
<eq><latex>\Lambda</latex></eq>
<eq><latex>\Pi</latex></eq>
<eq><latex>\Upsilon</latex></eq>
<eq><latex>\Psi</latex></eq>
</col>
</panel>

As a result we can (and eventually you will be able to) change the panels or add any new symbols that anyone might wish for. Creating whole new panels is also very easy, so please send me suggestions. One objective for the future is to have hundreds of different looks for the editor with cut down panels that focus on different realms of engineering, science and mathematics.

I'll get back to the TiddlyWiki code as soon as your happy with the above :)

Will.
