📑 I have found these related issues/pull requests This has been already suggested here: #6256 (comment) by @cyril59310 in the discussion of the PR of @TheBestPartOfMe to implement #6196. 🔖 Feature description On the dashboard page, one can drag-and-drop a monitor (or group of monitors) into a group. But once the monitor is in a group, it cannot be dragged out on the top of the hierarchy (one needs to go to the monitor, edit, monitor group, select, save). ✔️ Solution When dragging a monitor either... Right at the top of the monitors list Right at the bottom of the monitors list Also maybe, in-between any groups Then, dragged the monitor should be unlinked from the group it was, and be considered outside of any group I would suggest a big green bar when hovering in a position that would result in un-parenting the element (same color as the dotted line surrounding a group when hovering the dragged element to drop). Also, note that since elements are automatically sorted alpha

📑 I have found these related issues/pull requests This issue follows a discussion here: #7042 (comment) 🔖 Feature description Right now, upon new maintenance creation, start datetime and end datetime are not linked whatsoever: it's even possible to set a end time which predates the start time without raising any error. All of this could be slightly smarter. ✔️ Solution I see this issue in three parts: The end datetime could be modified dynamically upon modification of start datetime: When start date is changed manually, use the currently selected duration to re-compute the end date accordingly. For instance: Initial situation: Start date set to 24/02/2026 01:00 Duration set to 1 hour Implies end date set to 24/02/2026 02:00 Change: Start date changed to 24/02/2026 03:00 Provokes setting end date to 24/02/2026 04:00 The only exception to that should be when the user has already modified the end date manually. In that case, just select the matching duration, if appli
