Following your remarks and reports, we have made some modifications on the secure trade tool so as to make the make the characters selection easier and faster.
Please test it and let us know what you think about it. We find it better and we are thinking about using this pattern in other places.
It is very convenient.
But I did suggest you keep the old button also there as UM_AaaBattery said,in selecting clan wise or particular card wise it is hard.Also we have to know the name of the card,if it is a new card we might not know the name then itself as we may not be familiar with it.I suggest putting an easy select in Collection Pro also.
It was very painful to discover how this functionality works.
And much more painful is the necessity of switching between keyboard and mouse (type the staring characters - click on suggested card - press Enter - and so on). And even worse is that from now, I need to know the card names look for them in the second window. Even on a wide-screen display it hurts a lot.
(But the animated battlefield is very pleasant to me.)
