====== About the script ====== * Purpose : This is a script that places an item as an indicator always on top, that is replaced by the next one when reached. * Author : [[https://plus.google.com/u/1/105066926163073195690|TrianguloY]] * Link: https://plus.google.com/+TrianguloY/posts/CR2Mj15DTLe (with video) ====== How to use the script ====== Instructions: - Label the items "indicator 0", "indicator 1", and so on starting from top, otherwise it will behave wrong. - Unzoom (or zoom) to move all the items to their positions. Use this specially when editing. - Newly created items are prepared (tag saved and detached from grid) automatically. But - To modify a previously saved one, run the script from the item (to save only that item), or from the container (to save all items, make sure all are in the right position) Important note: For me it works smooth and lag-free with 3,4 items. Didn't tested with more but if it works slow for you, try to change the AUTOREFRESH to false, keeping in mind you will need to run the script after any change you make, even when adding new items. ====== Script code ====== <sxh javascript> //Indicators by +TrianguloY /*Reminder: the items need to be labeled "indicator 0" "indicator 1" "indicator 2" ...
