Hi,
I am a big fan of Trello.com.
There were however small things that could be better. This is why I created browser plugin to enhance it.
I have been polishing the plugin lately and thought you might find it useful as well.
Here is a shortlist of current features:
it can show card count per list
it can show total card count per board
it can increase labels and embed their name so that those are easier to see and understand
it can color the whole card with it's label color - this can be used as another dimension (I use it to mark priority)
visualizes card ID (useful for linking cards from comments)
I have been open on progress in this Trello board: https://trello.com/b/4Vgbr5e7/trello-improvements-add-on, where I also take requests.
Right now there are versions for:
Firefox https://addons.mozilla.org/en-US/firefox/addon/trello-improvements/
Chrome https://chrome.google.com/webstore/detail/trelloimprovements/cfajneojaaaagcahkajieaeaiegndpep
I am planning to dedicate a bit more time and make it easier to send feedback as well as gradually move towards a monetization, probably with freemium model.
I would love to hear your thoughts and suggestions.
Robert
