finally the first version of my so called PokerCraft Extensions is released. i have submitted to the microsoft edge addon store and it is now in verification process. i will provide the link as soon as it passed.
as said earlier the only feature so far are UI extensions for My Tournaments page to toggle Flip- or Go-Stages if listed at all.

so why did it take so long to implement this tiny feature. first of all i had to learn how to code some extension at all. it turned out that this is fairly easy. additionally i wanted to provide a good user experience and reliable functionality. the main work was to find hooks in PokerCraft and appropriate extension capabilities to inject code.
i will just describe the very first hurdle here. it is possible to inject code for arbitrary URL patterns. therefore my naive approach to extend My Tournaments page was to hook into
https://my.pokercraft.com/tournament*
this works as long as you call it directly. but PokerCraft is some kind of single page application launched with a different URL and navigation is done via client-side routing. that means when launching from the poker client my extension did not kick in. finally i hooked into the context root and implemented some navigation observer to enable injection of different code for different pages in PokerCraft.
depending on the number of target rows it could quite take some time to toggle them all. i have added some page blocker with a simple progress that is updated while toggling rows. this is implemented to be usable by all kind of future operation as well.

some needs to find some good balance between how many rows will be toggled in one cycle before updating the progress. i have added an option for that. the more rows you toggle the less responsive the UI will become. on the other hand toggling row by row will take more time compared to bulk processing.

and last but not least some possibility to support me and the development of this extension

for the next release i plan to add some footer to the tournement list summarizing selected entries. my final goal is to have that ROI shown without the limitations of currency alignments. e.g. one idea is to use some currency conversion service api to get conversions for the tourneys actual dates with some manual options as fallback.
feel free to ask for and request additional features you would like to be added.
