Updated observing planning tools, improved session workflow, and general stability improvements.

Version 18 build 1 is a major smart-telescope planning update with requested timing and workflow fixes: - Corrects checked-target planner timing so the first target starts at initialization, each next target starts at its first visible time, and the previous target ends there. - Handles after-midnight cascades correctly for observing windows such as 22:34 to 04:47. - Keeps the final target only through the earlier of its visible card end or the capture-window end, leaving unused time open for another target. - Tightens target availability checks so a target is rejected if any minute of the proposed segment falls outside the viewing window. - Keeps checked targets visible while switching object types, making mixed nebula, cluster, galaxy, and other plans easier to build. - Adds planner Fill Gaps suggestions for open windows between scheduled targets. - Adds Quick Ref PDF or text export for fast field use at the telescope. - Pads low-altitude ALT report values to two digits in plan, PDF, print, share, and Quick Ref output. - Adds telescope-specific Home timing, including shared Vaonis smart telescope timing based on the calibrated Vespera II Singularity field window. - Adds optional Weather Underground PWS current observations while Open-Meteo continues to fill unsupported cloud and forecast rows. - Resolves GPS-captured observing locations into address fields when iOS returns a placemark. - Warns before target database downloads begin because the dataset may be large. - Improves Clear Sky filtering across multiple azimuth/altitude zones. - Removes Hestia from smart telescope setup because it is a phone accessory, not a true smart telescope. - Updates About, Help, manuals, website materials, release screenshots, and the iOS logic-flow diagram. Also give the macOS version a look: https://bigskyastro.com/macos/user-manual.html

Version 17 build 2 improves planning, filtering, and field use: - Plan an observing night for a future date. - Filter targets by catalog, object type, magnitude, time, azimuth, altitude, and multiple Clear Sky openings. - Keep checked targets visible while switching object types to build mixed plans. - Use Quick Ref for target name, first view time, azimuth, and altitude. - Apply the less restrictive altitude where Clear Sky zones share a bearing. - Merge duplicate Messier, NGC, IC, Caldwell, and common-name aliases. - Restore older saved plans through improved target matching. - Restore the Telescope to Targets workflow and improve plan startup behavior. - Sort First View earliest first and Magnitude brightest first. - Use refreshed About, Help, manuals, and screenshots.

Version 16 improves target planning, filtering, field reporting, and release documentation: - Plan a future observing night from setup instead of only using the current date. - Filter targets by catalog, object type, magnitude, time, azimuth, altitude, and multiple Clear Sky openings. - Keeps checked targets visible when switching object types, making mixed nebula, cluster, galaxy, and other plans easier to build. - Adds a Quick Ref report with target name, first view time, azimuth, and altitude for fast use at the telescope. - Improves Clear Sky filtering across multiple azimuth/altitude zones, including shared bearings where the less restrictive altitude applies. - Merges duplicate catalog aliases into one target and restores saved plans that used older Messier, NGC, IC, Caldwell, or common-name entries. - Restores the Telescope to Targets continue flow and improves last-plan restore versus clean-plan startup. - Tightens sorting so First View is earliest first and Magnitude is brightest first. - Updates the in-app About text, bundled Help, website manual, App Store screenshot set, and iOS logic flow documentation.

Fixed black text on background. When saving a plan, made the name field stand out. Fixed light dark issue.

Added functionality to several areas. Including fixes to easier ways to change target information.
